I'm in the market for a used C5 or C6. Anyway I had a line on a beautiful 2001 convertible, probably would have made an offer on it, but one problem. I think my torso is too tall for it. When I first got in it my head was hitting the bar in the soft top, I managed to lean the seat back and move it back a bit and that problem was solved.
Unfortunately the sun visor seemed like it was just above my eye line blocking a bit of my peripheral vision. Moving it out of the way helped but I'd pretty much need to remove it permanently if I bought the car. Still feel I'm too tall for the car as I was still sitting too high for that really raked back winshield.
So I'm probably going to go with the C6 as I did not seem to have these problems in that car. Didn't have them in my 79 vett either. I REALLY wanted to like this car though, I think its gorgeous and had all the options I was looking for.
