Chevrolet Avalanche
If there’s one thing that GM does right, it’s an attempt to do something different. The Avalanche was a great SUV that offered an innovative design. It was the first SUV that turned into a truck via the back glass and the truck bed. The Avalanche proved to be a knockout success for GM in the long run, although it was eventually discontinued (via Every Car).
The SUV boom during the 2000s was a crazy time when almost every automaker was trying to jump into the mix. The design of the Avalanche was appealing enough that even the most traditional pickup truck buyers were willing to give it a chance. There was also a Cadillac version of the Avalanche.
