You may never know what you're going to find on eBay. The auction house of the interwebs routinely plays host to metal both obscure and unique – two categories the vehicle you see above satisfies without question. It's a 1964 Pontiac XP833 Banshee Concept, and while it's easy to think that the car is little more than a warmed over Corvette design, the truth is that this particular Poncho had widespread influence on General Motors design language for more than a decade.
Originally penned by none other than John Delorean, the Banshee was supposed to be a more sports-oriented competitor to the recently introduced Ford Mustang. Unfortunately, when the concept was completed, the higher-ups felt that the Banshee would threaten the Corvette throne and the project was scrapped. It's a song that would be repeated time and time again in the future.
