Like Joel said, you've got to consider that cars are being built better and more reliably. With that, a car that had more avg miles/ year probably experienced less start ups, drove at operating temperature more, etc than one that was not. It's not guarnteed, but you expect someone driving something 20,000+ miles a year doesn't drive 3 miles at a time, stopping and starting. If I were you, I would just make sure to have service records... you can tell ALOT about how a car was maintained by the regularity of oil changes. Mileage shouldn't scare you IMO, just look for a well cared for vehicle.
