will a C6 corvette car cover fit a C7?

Yes but not well. If you can afford a C-7, buy a C-7 cover. That way there will not be a rub marks where the body is different. First ask yourself, what are the different dimensions between the cars? Wider, taller or shorter, length, mirror larger/smaller, different placement? Hood longer or shorter? Body wider? Don't be a skimp artist, get what fits. OJ did just that remember and see how that turned out?

I beg to differ! Got my C7 last Aug and wanted a indoor cover but couldn't find any. Chevy didn't even have one. Did finally find one for $500. Being a owner of a 2009 C6 and having a cover from Corvette America (Premium Flannel), I tried it on. It fit like a glove at 1/3 the price. Bought it and it works fine. While I'm on the subject of C7, what is the little removal panel 2"X2" on the left rear under the bumper? No one seems to know!
