I'm 6 4 and I have excellent room in my Maser Gran Sport. Great Car!
Although I am guessing you are not interested in a Mazda MX-5 (Miata I think you call them) I am 6'3 and fit into my girlfriends MX-5 with no problem at all. (Good little car by the way that handles like its on rails, despite the reputation of being a chicks car)
