I agree with the above!!! I saw a 96 z28 camaro with 70k miles sold for 1500bucks. Clean(well it was dirty but you know) interior and body was great.
I know someone who buys cars from a police auction then fixes them up and sells them. Thats all he does. And he is living in a nice house!
Just be sure to check EVERYTHING on the car... We recently got a lincon something.. not sure what year but it was fairly new and it was in superb condition for like 2grand. on the drive home the car started shaking violently so we pulled over and took off the the hubs to find all but 1 bolt on the wheel had snapped off do to the bolts not being screwed on tight enough!!
lucky we cought that intime or that could have sucked.. :P
