A-bodies over priced?

I do question the leaf spring stance on a 16,000 mile car,,,a bit saggy,wouldn't you say...if I was going to pay top dollar,,,I would want to see some serious documenting
The front's just cranked up too high. Looks fine in back. Do you really need documentation for a 16,000 mile car? What documentation do you want? Can't you tell if things have been replaced, the car repainted, how much wear is on the car? You think someone can take a 100,000 mile, or even 50,000 mile car, and turn back the odometer and be able to fool anyone?
