Each car has its own history
It really depends on each and every car and you need to do your homework. These cars could get real old to someone who had no idea what they were buying (rough ride, insurance, repairs) which would mean nothing to a subsequent owner other than it changing hands a few times. The car would be fine and just looking for that right owner. On the other hand you could be buying a 'burned out' car that gets a new owner every 10k who runs the hell out of them.
Overall, it is probably best to look for that one or two owner car that has documented paperwork (maintenance) to ease your mind. I personally would prefer the latter. Good luck with your search.
