I have seen several come through delaer auctions with close to or 100K miles or so. There was one locally I looked at that had 75K on it. Everything mechanical seemed to actually work properly still from what I could determine. Although you could tell the engine wouldn't have been hurt at all by a tune up and valve adjustment. Then again this was a car that literally had a hole in the carpet on the drivers floor from a lack of floor mats as well as cigarette burns in the seats and the obviously used spare tire just sitting in the back of the car with some cheap looking 195 tires mounted all around. No wounder the LMPG was 45. Still it held up.
