My 6’5” son fits just fine. He’s pushing it on headroom, but he fits! If he were 6’7” there may be a problem.

I’m 6’3” and I think you could fit, but it might also depend on the seats. I’ve got the comp seats in mine...which I had to get used to at first, but now I really, really love. They have a weird way of wrapping around your body and keeping you well planted for all those ‘G’s

I will say that if you get in an accident, there’s not really anywhere to go. I’ve got the targa top (painted), and don’t like to think about what would happen if I rolled the car. If I were you, I’d go sit in a few at a dealer, just to make sure it’s right for you. The C7 is a totally different animal than the C6, and if you can comfortably sit in the C7, you’ll be very glad you did. Worst case scenario is you’d have to get a custom seat, but I don’t think they are too expensive.
