I would just make sure that everything works. Test it yourself because I have been told "oh yeah, it works" and later found out it doesn't. Also, be sure to check everything, down to the windshield wipers, turn signals, brake lights, etc, etc. Its much better to find problems before you buy rather than after. If you find them before, you can have them fixed or take a deduct on the price. If you find the after, thats too bad.
