The first crossfire I test drove was a black base coupe (what I wanted). I didn't start it properly the first time.... went to start it again and there was a pop sound. When I got it started it was idling rough. They kept hounding me and tried to sell the car to me. They told me the problem was fixed and it was a vacum line. At that point I didn't care because that problem turned me off. I thought it was a sign not to buy that particular car.
