The Financial Realities of Choosing A Safe Used Car for Your Teen Driver

cherokee - 1997 - publicdomain
Affordable cars aren’t necessarily safe ones

If you read this blog, you’ll know that I’m a fan of much of what the IIHS does, particularly with respect to their side impact tests, which I feel are more relevant to real life than the NHTSA’s side impact tests. However, there are a number of policies and practices they espouse that I either directly disagree with or find less than helpful. The institute recently came out with this list of, per their perspective, the best used vehicles for teen drivers. Here are my thoughts on it from a financial angle.

In the survey of parents, the mean purchase price for a teen’s vehicle was about $9,800, while the median was just $5,300. There are many options on the recommended list for under $10,000 but just three that cost less than $5,300.
“Unfortunately, it’s very difficult to get a safe vehicle for a teenager at the prices most people are paying,” says Anne McCartt, IIHS senior vice president for research. “Our advice to parents would be to remember the risks teens take and consider paying a little more.”

This is perhaps the section of the article that bothers me the most. The two lists provided by the IIHS are for vehicles under 20k and vehicles under 10k, yet at least 1/2 of vehicles chosen by parents are under 5.3k. The fact that the average price, 9.8k, is nearly twice that of the median, further indicates that very few parents actually spend 9.8k, but that a few parents are spending large amounts of money (e.g., those buying expensive new cars), which skews the average upward.

Averages can be deceiving when understanding human behavior

It’s sort of like the joke of how if 3 people in a restaurant have 10k each in net worth (e.g., Person A with a net worth of 5k, Person B with a net worth of 10k, and Person C with a net worth of 15k….this would result in both a median and mean, or average, of 10k) and a billionaire walks in, the “average” net worth in the restaurant jumps to 250 million dollars. However, that doesn’t make any of the other 3 people any richer, and the median remains at a far more reflective value of 12.5k (10k + 15k = 25k / 2 = 12.5k), rather than 250 million. A newspaper, television, or other dishonest source of information, however, would tell you that the folks at the restaurant were very well off. But it wouldn’t be true at all.

In other words, averages often have nothing to do with reality. Look for medians to find out what things actually look like on the ground and in the trenches.

With that said, it’s not very helpful to provide a list of expensive vehicles (from the perspective of the parents who actually buy the vehicles) with the knowledge that most parents aren’t going to spend anywhere near the values on the list. To the IIHS’ credit, they do acknowledge that only 3 vehicles on their list cost less than the median value. However, with a list of 95 vehicles, at least 47 should have been priced less than the median value for the list to be relevant to parents. Instead, 3 vehicles fall on the weaker side of the median (the ’06 Sedona, ’05 9-3, and ’06 Passat). That’s just not helpful.

Who are the most dangerous drivers? Not all teenagers are the same

At this point, you might state that the IIHS does encourage parents to spend more on vehicles for their teens. That is absolutely true. However, the problem isn’t that parents aren’t spending enough as much as that new vehicles cost far too much to begin with, which leads to used vehicles costing far more than they should. And statistically, while teenagers may be the most inexperienced drivers on the road (due to having the least amount of time behind the wheel), all teenagers don’t carry equal risks. When rates of involvement in fatal collisions are considered, which, to me, is as good a way as any of analyzing who the dangerous drivers are, the most dangerous drivers on the road in terms of age and gender groups are males between 16 and 29. “The risks teens take” would better be described as the risks males take, and implying that all teens need big vehicles to protect them from themselves is both patronizing and inaccurate. If anything, young male drivers should drive as little as possible until they turn 30, regardless of which vehicles they’re driving.

The IIHS knows this, as this information is available on their website here. I’ll have another post on that issue later (update: here!). But for now, I’ll end this post with noting that we don’t do parents (or teens) any favors by taking the time to research how much parents actually spend on vehicles for teenagers, and then providing a list of vehicles bearing no relation to the realities of parental budgets, and urging parents to spend more. Not in an economic climate where the cost of a full year of public school education (~25k) for one child is equivalent to half of the median household salary (~50k), and where healthcare eats up ever-larger portions of family finances. It doesn’t make sense.

I’ll also argue against the wisdom of encouraging the vehicular weight arms race by telling parents to buy their teenagers large SUVs and minivans at another time. But for now, my take home message is that promoting $20,000 and $10,000 vehicles for teens when most parents are spending well, well under these amounts does little to actually promote vehicular safety for teenagers.

Maxi-Cosi RodiFix Review: A 3-Across & 5-Step Friendly Booster!

Dorel has been in the car seat business for a long time, and I’ve had the pleasure of using a number of their seats on various trips around the country with my kids in the past. They offer seats up and down the line in terms of budget and child fit, and one of the newest offerings in the booster range from them is the RodiFix. Let’s take a look at it together.

2020 update: There haven’t been any significant changes to the RodiFix in the last few years besides slight fabric updates; weight and height limits remain the same, and this is still one of the three best dedicated boosters on the market (alongside the Clek Oobr and Peg Perego Flex 120).

Maxi-Cosi RodiFix – What’s the big deal?

The Maxi-Cosi RodiFix continues a tradition of high quality car seats by Maxi-Cosi (who brought us the Pria 70 with TinyFit convertible) that makes this one of the most impressive booster seats on the market. It’s a single mode booster car seat, which means it can be used in one configuration: as a high back booster and not as a backless booster. For parents of booster-age children, the Maxi-Cosi RodiFix is among the best boosters on the market.

Maxi-Cosi RodiFix Limits for Weight and Height

High back booster: 33-120 pounds, and between 34 and 57″ in height.  The seated shoulder height of the child isn’t anywhere in the manual, oddly enough, but after measuring it a few different ways, I’d state it’s close to 21.” Your child should be at least 4 years old. Of course, research into car safety indicates children should remain rear-facing for as long as possible (the average is 4 years in Sweden, which posts the lowest child fatality rate on Earth), and after rear-facing, the child should remain forward-facing as long as possible before switching into a booster.

Remember that children should remain in booster seats until their seat belts fit them over the shoulder, across the chest, and flat on the upper thighs. This is commonly known as the 5 step test, and it’s a great way to check to see when your child is ready to use an adult seat belt.

Dimensions of the Maxi-Cosi RodiFix

The seat is 12″ wide at the base of the seat, which makes it significantly easier to install than many boosters. The seat weighs 14.5 pounds, which makes it one of the lightest high back boosters out there, and definitely the lightest on the market right now with rigid LATCH attachments. There are no armrests.

Why Buy the Maxi-Cosi RodiFix?

I’ve had the privilege of reviewing some pretty awesome car seats over the last few years, both as a parent and as a grizzly guy writing a car safety blog. I advocate rear-facing to the limits, forward-facing to the limits, and only then switching to boosters. I prefer convertible seats to infant seats and combination seats to boosters, simply for efficiency. Dedicated boosters, in the end, are designed to do the same thing as combination seats in booster mode: to properly position seat belts on children who are old enough to sit in them. So if there are combination seats that do as good of a job as dedicated boosters, why would I review and even suggest a dedicated booster?

First of all, the Maxi-Cosi RodiFix has a rigid LATCH attachment instead of a flexible one. This is an attachment system that’s more secure than the typical flexible attachment found in most high-end boosters in North America. There’s also the word that the rigid LATCH configuration may prove more stable in side impact collisions, increasing the safety of children in the deadliest kinds of collisions. All you have to do when using the LATCH system to attach the RodiFix is to pull the connectors out and move the seat until it sits on your vehicle’s lower anchor bars. Similarly, the removal is also quite easy, as you can detach each side one at a time. When you aren’t using the connectors, you simply tuck them into the seat. Of course, using the connectors is optional, but it has a number of advantages already mentioned.  These are several reasons to like the RodiFix. However, there are more.

Something else I like about the Maxi-Cosi RodiFix is that the headrest comes with EPS foam throughout the inside and also is home to Dorel’s proprietary Air Protect Technology, which, according to Dorel, can reduce head injury risks in side impacts by up to 20%. Similarly, the torso wings of the RodiFix have lots more EPS foam to increase levels of side impact protection and reduce stress and strain on the body during collisions. All of these are good things. However, I also noticed that the foam did not have any plastic shell backing it, which gave the wings a rather delicate feel. I found myself being extra careful when moving the seat around during installations because I felt like the foam could crack if I bumped it into anything. It probably wouldn’t have, but it made me nervous.

You can fit the RodiFix in any car on the market

My favorite reason is the sheer ease of installation. Because it’s just 12 inches wide at the base, installation is just great in almost all conditions. It won’t work in every 3 across setup, but if you’re having trouble with buckling or with puzzling many seats in small spaces, this is likely to be the seat that’ll make boostering possible. This alone is reason enough to buy the RodiFix.

Beyond this, I like how padded and plus the Maxi-Cosi RodiFix looks and feels, as well as the fact that it comes with two recline positions. The armless element is unusual but can certainly come in handy during tight installations. However, keep in mind that the seat is on the narrow end, which means that if you have wider or stocky children, they might begin to complain before long. If your kids are average in width or slim, they’ll be fine.

Oh, and there aren’t cupholders. It’s a European seat (it’s made in Portugal), and those aren’t that big over there. I almost didn’t think to mention this, but it’s something that might make a difference to a child who loves his or her sugary drinks.

Finally, again, the Maxi-Cosi RodiFix is also simply an easier seat to install than most, due to its very narrow base width of 12 inches. That means it’s actually possible to install 3 across in a number of small vehicles.

The Maxi-Cosi RodiFix is a rather unique car seat and, in my opinion, one of the best booster car seats currently available in the United States for children above the age of 4.  It’s likely to be the last seat your child needs before s/he is ready for a regular adult seat belt.

Understanding the Physics of Car Crashes

ody03Understanding the physics of car crashes is essential to understanding a number of the things I talk about on this blog, including the forces that impact people and vehicles in collisions. This video from the IIHS is a good primer to some of the physics involved in car crashes.

For example, inertia, or the tendency of bodies in motion to remain in motion, is discussed and related to why wearing seat belts is always a good idea. Momentum, or mass x velocity, is also discussed, with the example of how an 80,000 lb semi traveling at 2 mph has the same momentum as a 4,000 lb SUV traveling at 40 mph. Impulse, or force multiplied by time, is exemplified by throwing an egg against a solid vs. a pliable surface and observing the results.

We are eggs. We need time to survive our collisions. This is why we have crumple zones, seat belts, and airbags. Watch the video and then look at some of the collisions on the blog; you might see them in a different light. This is why we safely restrain our children in car seats that spread out impact forces, as we want more physics on their side, not less.

Diono Radian R120 Review: Still Worth It! With RXT, R100 Comparisons

2020 Update: Diono’s gone on a renaming rampage. The Radian R120 is now the Radian 3RX. Practically speaking, it’s the same seat. Buy it here and enjoy extended rear-facing ang a good amount of forward-facing time in one of the absolute narrowest convertibles on the market.

2018 Update: The Radian R120, as well as all other Diono convertibles, were recalled in late 2017 by Diono and new versions were released addressing a potential safety issue involving top tethers. Every seat manufactured from October 2017 onward has been modified to resolve the issue.

Diono has released a number of high quality car seats lately, with their current flagship being the Diono Rainier. However, there are other, older convertibles by Diono that are still available and capable of keeping many children safe through extended rear facing. Today we’re going to take a closer look at one of them: the Diono Radian R120 All-In-One Convertible Car Seat.

Compared to the RXT and R100, it slots in the middle with the weight and height restrictions of the RXT but with the shape and lack of protruding headwings characteristic of the R00. Overall, it’s a blend of both seats and still one of the finest examples of an extended-rear facing seat capable of fitting in any vehicle on the market in 3 across configurations. You can read my full review below, and you can buy the Radian R120 here.

Diono Radian R120 – What’s the big deal?

Everyone today is talking about the Diono RainierPacifica, and Olympia. However, before they came out, Diono had already been establishing a tradition of narrow, high-weight car seats that are still worth considering even if they aren’t the newest seats on the market anymore. The Diono Radian R120 is an all-in-one convertible car seat, which means it can be used in several configurations, including as a rear-facing infant seat, a forward-facing seat, and as a booster. Despite its age, the Radian R120 is a car seat that should be on every parent’s shopping list. It’s essentially the same seat as the RXT but without the added head and side support, so this review will be quite similar besides a discussion about the parts not included in the R120 compared to the RXT. Skip down to the “Why Buy the Diono Radian R120?” section for the juicy bits.

Diono Radian R120 Limits for Weight and Height

Rear-facing: 5-45 pounds, and up to 44″ in height. Your child’s head should not reach past 1.5″ below the top of the headrest. This is a standard requirement among the Diono all-in-ones.

Forward-facing: 20-80 pounds, and up to 57″ in height. Your child should be at least 1, and it’s recommended that s/he is at least 2. Of course, research into car safety indicates children should remain rear-facing for as long as possible (the average is 4 years in Sweden, which posts the lowest child fatality rate on Earth), and after rear-facing, the child should remain forward-facing as long as possible.

Booster mode: 50-120 pounds, and up to 57″ in height. As with the latest Diono seats, the shoulders of the child must at least reach the 4th pair of harness slots. Remember that children should remain in booster seats until their seat belts fit them over the shoulder, across the chest, and flat on the upper thighs. This is known as the 5-step test, and your child should not leave a booster seat without it.

Dimensions of the Diono Radian R120

The seat is 17″ wide at its widest point, which is at the shoulders. The seat weighs 26.5 pounds. Inside, it is around 14″ wide at the widest upper portion at the shoulders and slightly larger at the thighs.

Using the Diono Radian R120

The seat arrives folded nicely in a box that seems well designed for it. The seat arrives in a collapsed mode, so you can hook straps up to it and tote it around as a backpack, which works really nicely if you’re planning on taking it on an airplane. It’s also airplane compliant, which is great for travelers. All of the LATCH straps are held in the back, including seat belt clips that may be needed for older cars.The engineering of the seat is solid, and you can see where the newer generations of Dionos came from when you look at the Radian R120.

You might need to adjust the straps out of the box, but the learning curve is gentle. Keep in mind that you cannot install it in the center of your vehicle with a LATCH set up unless you have dedicated LATCH hookups there; this is common to almost every car seat on the market today in the United States. This means you’ll need to use a seat belt installation along with a locking clip for a middle seat install, and this might be a bit troublesome.

The Radian R120 is highly adjustable thanks to the harness range

There are 5 shoulder harness positions that range from 9″ on the low end to 17.5″ on the high end. The recline base must be used when the seat is in a rear-facing position. Because there are 5 different slots for harness height, most children are going to find a position that fits them comfortably for as long as they use the seat. You adjust the harness height from behind the seat by removing straps from the splitting plate and rethreading them into the desired slot. If your child is rear-facing, the slots need to be at or below the shoulders, while they need to be above for forward-facing. Diono is unique in that they do allow you to have forward-facing children with shoulders above the top shoulder harness slots as long as these children stay within the forward-facing weight limit and have the tops of their ears below the top of the car seat.

There is an angle adjuster that is frequently sold alongside the Diono line, as it helps cut down on the extremely large amount of space that the seat can take up when used in the rear-facing configuration. Depending on the size of your vehicle and the amount of space you need in the front seats, you may want to consider purchasing this. This is likely to be the case if you set the seat up directly behind the passenger or driver seats in the first row.

Why Buy the Diono Radian R120?

This is the meat and potatoes of this car seat. The Radian R120 is one of a handful of seats in the United States that allows you to rear-face a child for up to 45 pounds. It’s not as good as it gets anymore, but it’s pretty close. Every pound is precious, as the longer you rear-face, the safer your child is. In the US, parents tend to turn their children around into the line of fire at 1. In Sweden, this typically isn’t done until 4. Children in Sweden are far less likely to die in car crashes than children in the US. It makes that much of a difference. This alone is reason enough to buy the Radian R120.

Besides that fact, the Radian R120 also includes a steel frame, although it does not include an aluminum reinforced headrest for reinforced head support or EPS foam around the child’s head and body to increase levels of side impact protection. The sidewalls are not as deep as those in similar Diono models, including its RXT sibling, which means you get slightly less side side protection. To be honest, this is the only real difference between the R120 and the RXT; if it matters to you, get the RXT. If it doesn’t, then the R120 will get the job done just as well.

The R120 might be a better Radian than the RXT

Some people even prefer the R120 to the RXT because some of the RXT wings had a bad habit of sliding down due to braces that were too weak to hold them in place over time. If you buy the R120, you never have to worry about this issue, much as people with cars with manual windows never have to worry about their window regulators going bad and leaving them with windows that won’t wind up in the middle of summer / winter / rainstorms / bad neighborhoods.

Finally, the Radian R120 is also simply an easier seat to install than most, due to its narrow width of 17 inches. That means it’s actually possible to install 3 across in a number of smaller vehicles. I also like the fact that it has a 10-year usable life when used as a booster and an 8 year life when used with a harness (remember, car seats do expire eventually), which is still among the longest in the industry right now, although not as long as the booster limits in the newer Dionos, which are 12 years. I also like that it is certified to use on airplanes when used with the harnesses.

What About the Newer Seats? – the Rainier in Particular?

The newer Diono seats are definitely flashier, come with longer product lives, and in the case of the Rainier and Pacifica, higher RF limits. However, none of this changes the effectiveness of the Radian R120. If you don’t need the newer belts and whistles or are looking to save a bit of money, I’d suggest looking seriously at the R120 alongside the newer Dionos.

The width point is particularly important to consider, as that’s an area where the R120 is clearly superior to the newer Dionos. I’ve compared both during installations, and there’s no question that the flaring out design of the sides of the newer Dionos makes them more difficult to puzzle with other car seats when trying to set up 3 across installations. It’s still possible to do 3 across with a new Diono, but not to the degree that it is with an older one like an R120 or an RXT. Keep this in mind if you’re driving a small class vehicle like a Prius, Civic, Corolla, Cruze, or any of the others I’ve reviewed here for 3 across compatibility.

The Radian R120 is an excellent car seat and, in my opinion, still one of the best currently available in the United States for children between zero and five.  You can buy the Diono Radian R120 in the three colors above here. Canadians can buy the Radian R120 here.

Diono Rainier vs. Radian RXT Comparison: What’s the Difference?

purplerainierThe Diono Rainier is one of the four seats with the highest rear-facing limits currently available in the United States. The other three are the Diono Pacifica, the Clek Foonf, and my personal favorite convertible car seat, the Clek Fllo.

The Rainier is essentially the direct descendant of and update to the Diono Radian RXT. On the outside, both seats look almost identical, with the exception of the flaring sides present on the Rainier.

Both seats are great, as I’ve discussed in my reviews of the RXT and the Rainier here, but if you’re a new parent, or a parent newly introduced to the wonderful idea of Extended Rear-Facing, you might have a hard time telling the difference between the two seats, and why the Rainier is worth around $100 more than the RXT, depending on which color you’re looking at. Here are my thoughts on the matter, based on my knowledge of both seats and experience with extended rear-facing.

Is the Rainier Worth It Over the RXT?

rxtIn short, I do think the extra for the Rainier is worth the difference under certain conditions, but not all. Looking at the seats on paper, you can RF to 50 pounds in the Rainier while to 45 pounds in the RXT. You can FF to 90 pounds in the Rainier and to 80 pounds in the RXT. The height limits are the same on both seats throughout the RF, FF, and booster ranges. The Rainier offers 2 more years of product life as a booster than the RXT at 12 vs. 10 years, but the harnessed lives remain the same. The Rainier is significantly wider to add to side impact protection. Those are the main differences.

With that said, I honestly think the RXT is as good as or perhaps a better value than the Rainier right now, given the price differential between the two seats. The 5 pound RF advantage of the Rainier is most relevant if you’ve got a heavier child; ditto with the 10 pound FF advantage. Since the top heights of both seats are the same, a child who would outgrow the RXT by height by 45 pounds wouldn’t get any more time RF in the Rainier. On the other hand, a heavier child could benefit from the increased weight limits, as the weight of a child doesn’t impact his or her safety when it comes to RF vs. FF; the position of the seat and the age of the child make far more of a difference. As noted here, the benefits of RF are visible in differential death rates for children at least up to 4 years of age, regardless of what the children weigh.

So should I buy the Rainier or the RXT?

I would recommend the Rainier over the RXT under the following conditions. Note that most of these points also apply to the Pacifica, which is essentially the same seat as the Rainier without the head wings.

1.) You want the best protection money can buy in a car seat for your children. There is no seat currently available in the US that offers a greater span of protection than the Diono Rainier, with its 50 lb rear-facing, 90 lb front-facing, and 120 lb booster range. Of course, the booster range isn’t going to be very useful for most children once they outgrow the FF range, due to the identical top harness height for the FF and booster modes, but that’s an issue common to all Diono seats, so I’m not going to hold that against the Rainier in particular.

2.) You’ve got a child who’s high in both weight percentiles and likely to surpass 45 pounds before turning 4 or 5, which is when I’d suggest forward-facing. Similarly, you’ve got a child who is not likely to outgrow the height limits of the Rainier before reaching 45 pounds; this means the child would be able to rear-face for longer in the Rainier due to the extra 5 pound window.

3.) You don’t need 3 across, or you have a large car, minivan, or SUV to do it in. By large, I mean a wide vehicle (ideally at least 75 inches wide). This is due to the sides of the Rainier; the bases of the seats are the same width, but the Rainier flares out significantly while the RXT does not. The width point is particularly important to consider, as that’s an area where the RXT is clearly superior to the newer Dionos.

I’ve compared both during installations, and there’s no question that the flaring out design of the sides of the newer Dionos makes them more difficult to puzzle with other car seats when trying to set up 3 across installations. It’s still possible to do 3 across with a new Diono, but not to the degree that it is with an older one like an RXT or a Radian. Keep this in mind if you’re driving a small class vehicle like a Prius, Civic, Corollla, or Insight. You might want to see what kinds of 3 across combinations are commonly used in your vehicle here.

4.) You want the extra side impact protection of the larger flared sidewalls of the Rainier. Diono claims they offer enhanced side protection compared to previous Diono seats and are packed with EPS foam. Given the speed with which side impacts can become severe, anything that can add an extra layer of safety and protection is certainly worth considering. Of course, keeping your child RF longer in an RXT will provide more side impact protection than FF in a Rainier, so keep the big picture in mind as well.

5.) You have a shorter child and want the assurance that s/he will be be able to make it from infancy through a boostering age. Because the Rainier offers 2 extra years of product life when used as a booster compared to the RXT, you’d have a better chance of the Rainier being the first, last, and only car seat you ever need. Of course, this will also depend on how your child grows, and keep in mind that most children aren’t ready for full seat belt use until they are between 10 and 12 years old.

6.) You have the extra $100. I generally don’t feel money should be a deciding factor when looking at ways to keep children from dying in motor vehicle collisions, but everyone’s got a budget, and this is going to be what makes the difference for some folks, and that’s okay.

If you can satisfy at least some of those conditions, then the Rainier is for you. If not, the RXT will also keep your child safe. The newer Diono seats are definitely flashier, come with longer product lives, and in the case of the Rainier and Pacifica, higher RF limits. However, none of this changes the effectiveness of the Radian RXT. If you don’t need the newer belts and whistles or are looking to save a bit of money, I’d suggest looking seriously at the RXT alongside the newer Dionos. At this level, your driving abilities will make much more of a difference than the seat. Drive the speed limit and rear-face to the limit in either seat.
