I sold cars for awhile. We had a grand am on the lot with a sweet spiff on it, but the car was run hard and put away wet, I really felt bad about selling it. Anyway, had a genius like that show up one day to look at it. I tried my level best to steer him towards some of the grand prix's we had that were in much better shape. He wouldn't have any of it and supposedly his brother was a mechanic so none of the problems were a real issue. Sold it to him, even making him fully aware that it was a terrible idea to buy that car. Needless to say, he broke down around midnight and had called the BBB on us and was trying to somehow declare that a used car was a lemon. Total idiot that really thought he knew more than he did. If the sales guy is telling you it's a bad idea, you better listen.
