To be truthful, there are only a handful of vehicles that are found en masse with more than 250K on them driving around like normal. Bugs, Volvo, Subaru, American pickups and Honda Accords and Civics. My MIL has a 94 Legacy that I went to the Legacy forums over. There is a guy in AK with a 600K example who's wife is driving a 400K example and his MIL's Legacy has 850K by his claims. My MIL's has 274K and the powertrain shows no fatigue other than being oily.
Dunno. I have a Saturn VUE and on the forum there are a bunch of guys with 250+ miles on their cars with very few issues. Most of them are way pass any resale value and are trying to drive them into the ground but the guy with most at 450k miles is still not able to do it. Of course some others meat more quick and unfortunate death
