4,500/year = lots of miles? I'd hardly say 73k is "lots of miles" but at least the car got some enjoyment and was likely maintained better than most of the cars running around here with 30k miles. People tend to think the 30k mile car doesn't need any servicing because it "only has 30k miles" where as the guy with 70k likely took it through it's scheduled maintenance as needed, which in the long run can potentially lead to a nicer vehicle.
For what it's worth, yes I make these statements based of personal and friends experiences.
FWIW, I speak from experience also...imagine that.
My first ('95) also had "lot of miles"....85K of them. Sure...I can do the quick math that you did, and come up with a "miles/year" figure, but wasn't my point. Point was that the more miles there are, the more likely you will run into an issue. Again....I know from experience.
Not quite sure where you made the assumption that a higher-miled car "was likely maintained better"? Or that a higher-miled car owner (however many there were) "likely took it through it's (sic) scheduled maintenance"?
Absolutely not true in my case, and not really an accurate blanket statement. Were you assuming those things because it still happens to be running?
The bottom line is, like I said earlier...do your research, look at the maintenance records, inspect the crap out of it, and pay a fair price based upon your DD.
