Victor Posted: 8/27/2008 12:25pm PDT I think the list is dominated by "green" cars, I don´t know if those concepts are the best from the General, this might be the "politically correct" list... Bob Posted: 8/27/2008 1:30pm PDT I agree Victor. How was the Sunraycer even a concept? I believe they built it for some particular competition. I could see the AUTOnomy earning a spot on the non-PC list, as it certainly was something unique and interesting. But the Volt and Impact, ehh... GM's got a lot more interesting concepts in its history than those.
