16: Pontiac Firebird
Another sports car that suffered from the lackluster design of the fourth generation F-Bodies was the Firebird. In some ways, the Firebird was uglier than the Camaro with which it shared a platform. The Firebird had an unorthodox design, to say the least. The curvaceous exterior didn’t mesh with everyone. Many automotive critics thought the exterior styling of the Firebird was a bit too extreme (via Classic).
Particularly when you got up to the WS6 or Formula packages, there would be added ground effects and even a wing. On most cars, this would add a sense of style, but on the Firebird it was way over the top. GM didn’t do enough to give the Firebird a unique look, instead, the car was cartoonish mixed with a boy racer. The final generation of the Pontiac Firebird is by far one of the ugliest sports cars around.
