I'm 6' 3" also and it doesn't bother me any sitting in the car for long periods of time. My suggestion would be to find one and just drive it around for a little bit and see what you think. You might also consider what you are buying the car for, Daily driver or just something to take out on the weekends or whenever. If you think that it is a little small inside then it might not be a good daily driver but if your getting it just for fun then it should be fine for you. In case your wondering about mine, it's not a daily driver. Jason #5903
