15: Chrysler Crossfire
On paper, the Crossfire seems like a great idea. Take Mercedes Benz engineering and give it a blue-collar appeal with a Chrysler badge. The Crossfire could have been a hit, as it shares a platform with the ever-popular SLK-320 roadster from Mercedes. But the design of the car was questionable at best, with some wondering what Chrysler was thinking. Take one look at the Crossfire, and you know that you aren’t looking at a normal sports car. The humpback design of the Crossfire was controversial at best (via Motor Biscuit).
Take the convertible version of the car, and you are just asking for trouble. The styling was by far one of the worst aspects of the Crossfire. Heck, the spoiler wasn’t even visible unless you were driving 40 MPH, at which point it would rise. These questionable design decisions made most drivers steer clear of the Crossfire. The sales were minuscule at best, and the car has become a flop in automotive history.
