I dont disagree.. I hate the plastic covers. Id rather see the engine. I guess when you have to appeal to the general public you have to make covers to make it visually appealing.. Oh well I am happy with either old school or new technology (minus the covers). Also depends on the look and style you are going after.
BACK ON TOPIC:
I would say most have already hit the common questions to ask about or look for. I agree with Charley too, I would offer him 18-20 and go from there; as long as everything else checked out. You can personalize it later on. Bottom line is if you like the car and it meets your standards then go for it.
