Found a car that I liked on a dealer website and went to see it and found it to be the dealer demo. The owner has been driving it and it has almost 5000 miles on it. Tried to negotiate 15% off MSRP because although they are selling it as new, it has been driven for 5000 miles and comparatively I was asking what the price of certified preowned with the same features are going for. The sales manager said he had only $500 of wiggle room, although the website showed a dealer discount of over $2000 which he never mentioned. How do I get this car for a price that is fair?
