Mileage is more on newer, more expensive cars.
On $2000 cars, condition is more important but mileage still matters.
You simply cant be very picky when you've only got $2000. You might find a lower mileage car but it might take a month or so of searching.
But, you shouldn't ignore a higher mileage car in great condition.
100 highway miles are easier on a car than 50 stop & go short trip city miles.
But, with $2000, you cant expect new, You wont get it.
About 6 years ago, I was getting out of the car business and wanted a cheap car for myself since I wouldn't have a for sale car to drive like I always used to. I was still a dealer and went to a local dealer only auction that a mega dealer has to dispose of his trade ins.
There were 2 cars I was interested in that night. a really nice 94 Honda Accord in great shape with 150k miles. I loved that car but I knew it was going to be expensive. You cant steal a nice import.
I had convinced myself to pay about $2800 plus the buyers fee for the Honda which was a lot but I figured it might take that much to buy it. As it turns out, it sold for $3500 plus the buyers fee which was probably $160 at the time. That's $3660 total.
The other car I was interested in was a 94 Buick Century. It was not as nice & clean as the honda but it was very low mileage and was obviously owned by an old lady. It had 59,000 miles, a crack in the windshield and the AC, while working, needed a freon charge. And the drivers side rear window wouldn't roll up. You could pull it up & it would stay up but you'd have to do it every time you roll it down. It also had a scratch in the middle of the hood, but I knew that most of that would buff out with some wax & elbow grease. Oh and it had a cracked headlight but the light still worked, it had dampness and I sort of figured that the water inside would cause the headlight to go out.
Since I was interested in that car, I also looked at another 94 Buick Century with 200k miles but it was real nice and it was hard to believe it had 200k miles. I wasn't willing to buy it because of the mileage though, It sold for $1000+ buyers fee.
My car went later and I was determined to buy it even though it wasn't as nice as the honda, I knew it would cost far less. I ended up paying $1725 plus the buyers fee of $90=$1815 total.
Now, 6 years later, I still have it. The crack in the windshield got worse. it was over about 15% of the windshield, now its over about 75% but its below my field of vision and I cant justify replacing it on such a cheap car. I charged the AC and had some stop leak put in it and its been fine. The headlight hasn't went out. The broken window is still broken, I just don't use it.And the automatic door lock on the rear passenger side door still doesn't work, I have to manually reach in there to lock & unlock it which is a pain.
Now, that was at a dealer only auction, retail prices would have been much higher.
I drive very little so my Buick only has 80,000 miles now. Ive had to do some things to it, like an alternator, a water pump, brakes, twice and tires. Oh and I flushed & refilled the radiator twice, It was nasty when I bought it and it was nasty 5 years later when the water pump went out.
I feel fortunate to have gotten 6 years out of the car without a motor or transmission going out but part of that is because Ive only put 21,000 miles on the car.
You might be thinking why do I drive such a cheap car when I can probably afford something much nicer.
Im thrifty and 15+ years in the car business taught me how much money people waste on expensive, depreciating cars.
I keep my money working FOR me rather than buying expensive cars that quickly depreciate.
Plus, I save a lot on insurance by having liability only.
I figure my cheap car has cost me maybe $1200 over the last 6 years counting the repairs that a newer car wouldn't have needed and depreciation. Compare that to someone who leases at $300 a month and gets a new car every 3 years with $700 down. They spent $23,000 plus insurance which was likely 4-5 times higher than mine.
Driving a newer, nicer car isn't worth that much to me.
I let my money work for me. Many people work their butts off so they can have a new car.
The above example is only 6 years but over 30-40 years it could easily be the difference between retiring rich and being flat broke. Especially when you add investment returns.
