I work for a big rental car company around the maintenance shop. The cars aren't really abused that much (with exceptions of course, but it's usually easy to recognize those) and they get a lot of preventative maintenance. The most common thing people do is get them FILTHY.

Just look at the tires to see their condition and inside the wheelwells for rubber bits and underneath for dirt and mud and it should give you an idea of the life it's had. Almost all of the cars go off rental to sale status for mileage numbers.
