Watch for fluid leaks or thing that look like they have been cut. Listen to it run, make sure everything is working ok. Lights, parking brake, windows etc. Check to see if you can see anything that looks goofy with the wiring harnesses. See if the guy that has the car did the install or had a shop do it. Get a little background on the car.

Let him drive it, it may show you how he really drives. Kinda sounds dumb, but it makes sense if you think about it. Let it run for a while and make sure its staying cool enough.
