Help me buy my first demon.

I totally agree with Judge Mills, that Demon is definitely not worth $3,000. Primer tends to hide alot of rust, bondo and bad patches. There is a fair amount of rust on that car and I will bet you once you get into it you will find alot more. How solid are the frame rails, torsion bar crossmember, rear shackle mounts and spring mounts, inner fenders, rocker panels, firewall, tailpanel, rad support, windshield and trunk channels, roof? These are all common rust areas on A-Bodies and are often hidden by undercoating, primer, bondo or other interesting patches. Go over the car with a fine tooth comb! Use a magnet to search for bondo. Get under it with a flashlight and a small mirror.

Judging by those pictures that car is worth no more than $1,500 max. It is only a 318 car, the standard is a plus but the fact that it needs 2 quarters, most likely also trunk extensions, drivers floor and a trunk floor 3 grand is way to much for a 318 3spd car.
