Re: 1995 RT/10 for 6\'5
I'm 6'5. It's tight in my RT/10. Without the top on, the main issue is that straight ahead in your line of vision is the top of the windshield. Slouching a little helps.
With the hardtop on, I fit, but with literally no room to spare (note, I am not sure if I have a factory or aftermarket top, look at
http://viper.lamba.ca for pics). Have never tried with a soft top.
Also my knees are almost always up against the panel.
I plan to get the seat lowering kit soon.
That being said, although I might fit better if I was 5 inches shorter, I love the car and wouldn't trade it for anything. I'm sure you can find someone local who will let you sit in theirs.
