3. Chevrolet SSR

In the midst of the mid-2000s retro craze, the Chevrolet development team came up with a crazy idea to produce a nostalgic two-sear 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 in the 2000s, so the SSR was just plain odd.

Despite many efforts to make the SSR appealing to its intended audience, Chevrolet managed to sell only around 24,000 of these oddballs. It was a painful realization that they need much more than a wild imagination to make such a concept work. Simply, the SSR wasn’t a Corvette and it wasn’t a truck. It was just plain pointless.
