I would have no problem driving my car as long and far as I can, which hopefully will be deep into the 100k range, hoping for 200k.
The difference is that I bought it new, and maintain the hell out of it.
In todays world of 15k oil changes, there is no way I would buy a car with 100k on it unless you follow El Karacho's point below.
I don't think he is saying that at all. See his above point.
I agree that finding a well documented car can be done, and I would purchase said car, but its not the norm.
