A good thing you could do, if you can go see the car, do a bondo nock test around the heavy rust area's on the car, and also, in the door openings, on the bottom corners, rear and front, they tend to rust there, which it seems that's where the car needs work. Also, take a computer hard drive magnet, carfully, hold it a few inches from the metal surface, hold it and move it around tightly in your hand, if the magnet lets up, that's bondo in that spot. DO NOT let go of the magnet, you will find yourself paying the owner for dent removal because it will snap at the metal and could very well den't it because they are very very strong. Also, don't hold them near TV's or computer monitors ( CRT monitors ) without a degausse function, it will permanently magnatize it and will show multi color around the edges but, it's fun ( turns entire screen into a rainbow whail still showing the picture ) as long as the tv or monitor has a degausse function. The function can be reconized with the humm heard 1ce the appliance is turned on, that discharges magnatism and static electricity.
