New Car every 10 years or Used Car every 5?
David asked an interesting question in the comments section of “Best and Worst Used Cars of 2007“, the question was:
.. is it cheaper to buy a used car every 5 years, or a new one every 10 – 12? I currently have a ‘95 Dakota (needed a new rear diff this year (caused by towing?) and the ECU died). Once the loan was paid, I had 7.5 years of trouble-and repair-free driving. I still have it, but bought a smaller vehicle this year (also new) which I expect to keep for a similar lifespan. The new vehicle has a 7 year bumper to bumper warranty, so I should have no repair expense during that time.
Doing some research around the net, it seems that cars depreciate 20% right off the lot in addition to the regular 7-12% depreciation / year. Of course this depends on the make/model of your car, features, colour, KM’s etc.
For the sake of simplicity, we’ll assume 32% depreciation in the first year, along with 12% depreciation every year after that. You guys can check the Canadian Black Book to confirm the depreciation of your favorite car maker/model. I tested these numbers on Hyundai’s and they are spot on. However, Honda’s/Toyota’s hold their values better.
- Year : Residual Value
- MSRP: 100%
- 1st year: 68%
- 2nd year: 60%
- 3rd year: 53%
- 4th year: 46%
- 5th year: 41%
- 6th year: 36%
- 7th year: 32%
- 8th year: 28%
- 9th year: 24%
- 10th year: 22%
- 11th year: 19%
- 12th year: 17%
The biggest factor that we need to account for between new and used cars are the repair costs. These costs typically start after the new car warranty expires. We’ll assume the bumper to bumper warranty expires after 3 years at which time the repair bill starts rolling in.
We’ll start the repair/maintenance costs at $600/yr increasing by 15% every year, starting @ year 4. In terms of the car, we’ll pick a fairly economical car that has an MSRP of $20,000.
| Year | Residual Value | Repair Cost |
| 1 | $13,600 | 0 |
| 2 | $11,968 | 0 |
| 3 | $10,531.84 | 0 |
| 4 | $9,268.02 | $600 |
| 5 | $8,155.86 | $690 |
| 6 | $7,177.15 | $793.50 |
| 7 | $6,315.90 | $912.53 |
| 8 | $5,557.99 | $1,049.40 |
| 9 | $4,891.03 | $1,206.81 |
| 10 | $4,304.11 | $1,387.84 |
| 11 | $3,787.61 | $1,596.01 |
| 12 | $3,333.10 | $1,835.41 |
Buying this new car every 10 years would result in a total cost of (not accounting for financing charges):
- MSRP – residual value + repair costs
- $20,000 – $4,304.11 + $6,640.08 = $22,335.97 (could be more if you get low-balled on your trade-in)
Buying this car once it’s 2 years old for around $13,000 (after small dealer markup) and keeping it for 5 years then buying another 2 year old car for another 5 (for a total of 10 years of driving):
- Purchase price – residual value @ year 7 + repair costs (from years 2-7)
- $13,000 – $6,315.90 + $2,996.03 = $9,680.13 x 2 = $19,360.26
Conclusions:
It appears that buying a used car every 5 years would be less expensive than purchasing a new car every 10 years. Of course, pretty big assumptions were made in this post so the calculations were meant to be relative.
I think the biggest issue with new cars is the massive depreciation after the first year. If you are a new car person, why not buy an “almost new” car that is one or two years old? At least that way you still get the new car feel, intact warranty, AND you don’t need to pay for the initial 30% depreciation.

Bought a 1994 Volvo 850 in 2009 with 223,000 kilometers in MINT condition.
It now has 390,000 kilometers and still in MINT. No rust at all I wash it 2 times a week.
I have changed rotors and pads 2 times ,PCV cleaning, Timing belt,idler pully,tentioner pulley,radiator and upper and lower radiator hose. bought the car for $1.360.00 and $2,500.00 in maintainance in 7 years. Did a compression Test to see how much life is in the motor it is within Factory specs. I owned 30 cars every make and model, This has been hands down the most reliable car. Ask yourself if You buy a new car for $35,000.00 and put 167,000 kilometers on it in 7 years. How much is it worth ? maybe $10,000.00 I cost You $25,000.00 to drive 7 years. It cost me $2,500.00 to drive for 7 years. Its still drives like a new car,does not burn a drop of oil or oil leaks of any kind It has never refused to start in The COLDEST of days. If you want to know how good these cars are go to YouTube ,type Robert DIY
I think new cars are a better option, depreciation be damned. There’s an infographic that actually shows off all that stuff.
Take look at it here: http://blog.unhaggle.com/new-used-car-buy-infographic/
Yeah but what about the fact that my new car will be financed at 0% for 84 months and a used car would be more around 5 %… I believe that if you buy a new car from the year before at the good moment or buy a demo and take care of your car for up to 10 years , it will be the cheapest way to own a car.
Now i feel a bit silly. Basically Chris wrote the same thing so much better a few comments up, thanks Chris! I totally agree. 5-7 years and 5k is a sweet spot!
I own a 97 lexus es300. I bought it in November 2011 for 3,500 and it had 180,000 km on it. It came with all service records and I am handy so I have made small repairs to it as required (sensor, some lubrication, oil changes). It is not painless to maintain but its reliable. Its a v6 but I think thats part of the reason why its more reliable than a smaller car of the same age.
Personally, I hate car payments. they are like golden cages that suck your money/value. But i did buy a rather old car with medium range fuel economy.
Its a strong car, and starts up in -25 with no issues, everyday, hasnt broken down and has lots of toys.
Basically, though, its hard to find a good used car, and most people dont put in the effort. But the “myth” of a new car being a safe car is overblown. A used car is pefectly fine if its a good make.
Being a bit wiser, I’d buy a 2004/2005 toyota corolla or a mazada3 today at about 5-6k and drive it into the ground.
While a car is a very personal choice, basically for 8K or under you CAN get a great compact that will do your daily commuter runs/chores for 5-8 years. Choose something dull, with 4 doors. Insurance is lower then too. If its a good brand and you keep up with the maintenance schedule (you should for ANY car you have) it should make alot of financial sense!
Get your car amortization to $100/month. Its possible…but its not flashy! lol
One more thought! I keep my records all written down, inspections, oil/filter purchases, tranny fluid, brake parts, and its running me on avg right around $250/yr mtc (doing work myself obviously). At time of sale, this car will cost me $1500/yr depreciation, pretty good for a model that between 0-2 years is about $4500/yr, and 0-4 is about $3500/yr. So my math tells me, i’m running an ex-l model for half what buying a new one and trading in costs. Every scenario where I buy new and keep X years (unless X=25 maybe), says used is cheaper!
Just a thought, why did you say new every 10 or used every 5, why not compare the annual cost of buying a used car when the depreciation has been paid by original owner. Anyone who thinks a 2 year old accord can miss THAT MUCH maintenance, dealer or otherwise, is missing the boat. I am going out on a limb, and say EVERYONE gets their oil changed (yes you all have your story about your idiot neighbor that forgot to do it for 6 years, but in general, people change oil!) A 2 year old honda will not need much more than that! So take that honda bought 2 years old, and drive it 8 years, and compare THAT to your buy new keep 10, this will make a real good case for buying a used car. I personally am just about ready to get rid of my accord, bought 2 years old, going on 8 I’ve had it, MTC is next to non-existant, 2 sets of brakes front and rear (2nd rear only becuase caliper ceased), and an engine coolant temperature sensor, 2 sets of tires, and oil & tranny fluid change, thats all that car asked for in 100k miles!
Don’t forget lots of people use financing to buy the new car… buying used is sometimes about paying with cash especially if you want to get a better deal in a private sale. If you know what to look for you can pick up really nice used cars for 5000 bucks and they can last.
Then learn to fix the simple things and save the big shet for the mechanics and you will save 15000 bucks. I think buying cars that between 5-7 years old give you the best price point… but you will never know that new car smell.
Note- The first owner of my jeep bought it for 33,000… the second owner payed 15,000 3.5 years later. 1.5 years later I bought it for 10,500.. inspection done.. only needs fluid changed.
[…] but not that great a deal if you’re a cash buyer. If we do go new, we hope to drive the vehicle for at least 10 years. In addition to “factory incentives”, the dealership themselves should have some […]
I disagree with the 32% drop the first year. Should be more like 20%. This changes the equation considerably (and the result). Plus the car insurance should change with age. Who is going to pay full coverage for collision on a car that’s only worth $5k?
