2. Chevrolet SSR

In the midst of the mid-2000s retro craze, the Chevrolet development team wanted to produce a nostalgic two-seater convertible pickup with muscle car performance. The result was the SSR, a vehicle that looked unlike any other car on the market and not necessarily in a good way. The 1950s-inspired design didn’t work well, so the SSR looked just plain ugly.

Despite many efforts to make the SSR appealing to its intended audience, Chevrolet only sold approximately 24,000 of these oddballs. That was a painful realization Chevrolet needed much more than a wild imagination to make that crazy concept work.
