Drive it. In town, and especially on the highway. (while you're on the highway, stomp on it, and observe your eyes open, and your heartbeat go up)
Start it a couple of times....make sure that $%^%$ check engine light doesn't come on. If it does, negotiate the price big time (after having found the cause of the light)
Be prepared to want to keep this car for a long time.
(I also prefer the look of the '94 &'95's)
