I'm going to give you my opinion and you can take it for what it's worth. I've driven the new Camaro's, Vettes, Porshces etc.. They are all tight and small on the inside but that's the way there supposed to be. That being said, I personally don't like the new Camaro's and this is coming from a guy that's owned two of the older models in his life and love them. Everyone I talk to whether they like the car or not say's you can't see out the windows. I couldn't see out the windows when I test drove one while buying my Tahoe. I didn't like it at all. That coupled with the cheap plastic inside.
On to the Corvette. To me the Corvette is just a much classier car and there arent a million of them on the road like the Camaro's. Also, you can't see out of them either but if it's a convertible your going to have the top down in nice weather.
If it were me I'd get a black Corvette w/removable top but that's just me.
Have fun with whatever you decide.
