Chevrolet SSR

Amid the mid-2000s retro craze, the Chevy development team came up with a crazy idea to produce a nostalgic two-seater convertible pickup with muscle car performance. The result was the SSR, a vehicle that looked different from any other car on the market, and not necessarily in a good way. The 1950s-inspired design didn’t work well, so the SSR was simply ugly (via Edmunds).

Despite many efforts to make the SSR appealing to the intended audience, Chevrolet only managed to sell around 24,000 of these oddballs in a painful realization that they needed much more than wild imagination to make the concept work.
