In 2018 my wife bought a used Mazda 5 for $3500 that only had 68,000 miles on it. Reason the guy sold it cheap is his daughter had been driving it and had managed to ding every corner. They are not that bad and we don't really care. Car now has about 150,000 miles and still running strong, though I had to replace the suspension (front struts, rear struts, rear coil springs). Other than that, it is a great little (mini mini) van.
I don't want a perfect car, prefer the faded paint look etc, but no rust please.
