31. Chevrolet SSR
In the midst of the mid-2000s retro craze, the Chevrolet development team came up with the crazy idea 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, but not necessarily in a good way. The 1950s-inspired design didn’t work well, so the SSR looked just plain odd.
Despite many efforts to make the SSR appealing to their intended audience, Chevrolet managed to sell just around 24,000 of these oddballs. The SSR was a painful realization they needed much more than a wild imagination to make a concept work.
