I'm 6"5" and I sit comfortably in my 96 Integra. I even spike my hair. My hair rubs from time to time, but otherwise, just drive and slouch. I don't think the headliners that much of a problem. You always could get creative and custom weld a new location for your seat.... I've thought about it since my legs are always bent while driving.

Anyone ever sat in a CRX? Those cars have a lot of legroom.
