That's not really true. I checked out a 93 Coupe with 33,000 km on it. it was rotten as can be. Yet, I know someone with a kouki S14 with over 400,000km and it's pristine. Mileage vs. condition isn't the best way to judge. Some people drive theirs cars a lot, but also take immaculate care of it.
Thats cause we live in Canada. US cars don't rot like ours.
