It's surprising, considering that Chrysler and GM are in the same town, that GM didn't learn from the Plymouth Prowler episode. When GM decided to kick up some custom retro mojo, it commissioned the Chevy SSR, an awesome-looking hotrod pickup truck with composite body panels and a slick convertible top. Alas, the chassis and mechanicals for the SSR were borrowed from GM's corporate midsize SUV program, making the putative performance machine heavy, underpowered and unforgivably lazy. It was no more hotrod than Britney is the next Helen Mirren. In the next couple of years, Chevy amped up the SSR but by then the credibility was gone. The SSR also violated a principle of hotrodding. Hotrods are homemade subversions of the existing order, mechanical folk art. There is no such thing as a factory hotrod. Seems obvious, in retrospect.
