$5k would actually be a pretty good deal.

Is the car stock? Beyond the basics, I think the most important thing to check for are signs of a past life as a ricer. A lot of these cars were beat on pretty badly. Check for unusual wiring or any signs of aftermarket parts. Once you get the car, get an alarm and take the ECU or fuel relay (or anything that would immobilize the car) out whenever you park it. This car is a major theft magnet.
