The most popular post on the blog by far is: Buying A New Car Is A Crazy Bad Idea. The comments continue to pour in almost every day with some wholeheartedly agreeing and others… not so much.
The ‘not so much’ crowd tends to point to things like reliability and the cost of repairs on older vehicles as the big reason to buy a new car vs keeping an older one.
So I did some research. A whole bunch of research. And I have the answer.
First of all, full transparency, I personally bought a new 2012 Ford Escape 7 years ago. We needed a vehicle that could hold our big golden retriever and my wife was secretly plotting to start a family so she wanted a vehicle with some room for car seats.
I love our Escape. It’s been a great vehicle. I don’t want to jinx anything here but it’s never had a major issue. I have changed the oil regularly and done a few other minor maintenance items myself. That’s it. I haven’t even had to do the brakes yet.
If I had to ballpark it I would guess we have spent $200 or less per year in maintenance on it since we have owned it. I realize some bigger expenses are just out on the horizon but still, 7 years and under $1500 spent on maintenance. That is awesome!
But I still view buying that car new as a financial mistake.
Seems crazy right? Its reliable, has fit our needs as a family, still going strong after 7 years…
But like the article I referenced before mentions I could have bought the same vehicle 5 years later for half the cost.
With that in mind it got me thinking, at what point is it less expensive to just buy a new car vs maintaining an old one?
To be clear I’m not talking about buying a reliable used car vs keeping an old one, though this will paint a picture for that as well. This is specifically to look at the typical person who buys a newish vehicle every 5-7 years and to see if they are making a good decision to avoid the costly repairs that their 5-7 year old vehicle is about to need.
To find out, first I looked at the average cost of repairs by mileage.
I was shocked at how high they were. But here it is per yourmechanic.com:
Mileage Cost
0-25k $1,400
25-50k $2,200
50-75k $3,000
75-100k $3,900
100-125k $4,100
125-150k $4,400
150-175k $4,800
175-200k $5,000
A couple of quick things to note: The average person drives about 13,000 miles per year. To make it easy let’s use 12,500 as the average. This means each of the categories above would represent 2 years of driving.
For example in the 2 years from 75-100k miles the average car owner spends $3,900 or $1950 per year.
Another item that jumps out is that the cost goes drastically higher as you close in on 100k miles, but then it starts to slow down and stabilize.
The last thing I want to mention here is that car repairs are ridiculously expensive if done by a mechanic. If at all possible, do the basics on your own and you will save thousands of dollars. (That is a post for another day)
Alright, just below this I put a nice chart together to show the cost of 3 typical car buying habits.
The first I call the “Always New” buyer. They buy a new car with a loan every 6 years.
To add up the cost I used the average new car payment per year in 2018 as listed by NerdWallet.
I did not account for inflation over the 16 years we are looking at meaning the buyer gets the exact same price and deal the next time they buy a car. Also I am using average payments as the cost so I am not including the trade in value of the car at the next purchase because that would be factored into the average new car payment already.
I realize it’s not perfectly realistic, but it’s also not too far off.
Second I have a buyer that I call “Mr. Drive It Into The Ground.” They buy a new car with a loan but then proceed to drive it until the wheels fall off which in this case is 16 years and 200k miles later.
I know people who like this strategy and have followed through on it successfully.
Last I have the “Responsible Used Car Buyer.” They buy a 5 year old vehicle with 62.5k miles on it for $10,000 cash. I know this is realistic because I did it less than 2 years ago to get a commuter car. And the car I got had fewer miles.
This buyer also drives their car until the wheels fall off which is 200k miles. But because they bought the car used it won’t last the full 16 years. They will have to buy another $10,000 used car after at the end of year 11. Remember we aren’t accounting for inflation in the second purchase price.
Here is the result:

The “Always New” buyer spends a little more than $118,000 over the 16 years on payments and maintenance. They do spend the least on maintenance at just $16,800.
The “Drive It Into The Ground” buyer spends $65,000 over the same time frame with $28,800 on repairs/maintenance. Not bad.
The “Responsible Used Car Buyer” spends the least at $53,000 over 16 years. Its still the least even considering that they bought a second used car in that time frame and spent the most on maintenance at $33,000.
I was surprised to see the drive it into the ground strategy do almost as well as the used car buyer strategy. It was still $12,000 more expensive, but by getting something new they at least had the peace of mind knowing exactly how well the car was maintained over its lifespan. (I don’t feel as bad about buying that new car that I plan to drive until the wheels fall off)
Also important, if instead they had bought the new car with cash it would have saved some additional money on interest making the results even closer.
What did not surprise me was that getting a new vehicle every 6 or so years is REALLY EXPENSIVE. A good chunk of that money is going to interest on the loan and the benefit of a new car every 6 years. Those things alone far outweigh the cost of maintenance in the other two scenarios.
I realize that there are other factors that could be included in this exercise. Things like insurance, taxes, licensing fees, and the fact the some types of cars are more affordable/reliable than others. But I wanted to keep it simple and use averages.
And including the other factors is not going to make enough difference to sway the results.
Plus if you wanted to get really technical the drive it into the ground and used car buyers could invest the difference that they saved to create even more of a win long term.
(Another reason to use that Acorns account!)
Here is the bottom line though: Everyone’s situation is different.
If you are out there crushing your financial goals, out of debt, and paying cash for a new car just because it’s fun to own one. Awesome!
In that position you already know the cost of vehicle ownership and you can afford to pay for the privilege of that new car smell.
But the reality is that close to 8 out of 10 Americans are living paycheck to paycheck and they don’t have money in savings. For that large group spending TENS OF THOUSANDS of extra dollars on a new car every 6 or so years is derailing their ability to reach their financial goals.
Instead, getting a reliable used vehicle at an affordable price, preferably with cash if at all possible, will free up those tens of thousands of dollars to help pay off debt and to save for emergencies.
Winning with money is about making choices that help you to win. If you weren’t sure what choice was best before, this example lays out exactly how you can possibly gain an extra $50,000-$60,000 over the next 16 years.
To put that into context, for most people that is a whole year of working.
How far could that money go in helping you to reach your financial goals?
It could pay off your student loans faster. It could pay for the travel that you have been dreaming about. It could put your kids through college. It could help you pay off your mortgage or save up for the lake house you want when you retire.
Think of the possibilities. Every day we make choices that impact our financial future. Make the choices that help you to win with money and to chase down the things that matter most in your life.
