The Chevelle Project website is a polished affair the presents each proposed model with a gallery of renderings from multiple angles; a spec sheet that includes powertrain choices, mileages, dimensions and capacities; a chart that compares each model with potential competitors; and an Overview page full of marketing speak that could've been written by General Motors itself.
It's quite remarkable how far the Cheers and Gears Underground people went with their efforts. The Chevelle Project took a year and a half to complete and was announced on March 15th, 2005. The site does say that more nameplates will get the "Underground" treatment in the future, so hopefully we'll see another model from them in the near future.
