I dont think it will be that bad. You might see prices drop a little, but I dont think its anything to worry about. The whole economy will be affected. Unfortunately, to the people who dont know anything about them, they might automatically assume "V8 = shit gas milage"... But theyre prob. not the ones looking to buy a 03/04 Cobra, GT500, or SS's. Theyre going to be getting the sixxers anyway because they dont know the difference. So, I think all you Cobra/GT500/Mach 1/GT owners are going to be fine. People dont buy them for the gas milage. They buy them because theyre fun, and getting pretty good gas milage is a plus.
