Got any pics of your supra?
oh, and good luck finding one in the $400 range. The only way I can see that possible is if the motor does not run at all (or isn't even in there) and the car is covered in rust. Other then that, if the car was in semi-decent shape then the person selling it would probably know that they could get more than $400 for it by just raising the price a little or even parting it out.
