I am 5'11" and weigh 250. I have owned an NA Coupe, and currently own both an SRT6 Roadster and Coupe. The cars are actually pretty flexible interior wise. The drive seat is a six way adjustable. It takes some time to get the seat spot on, but when you do its well worth the time spent adjusting. In my coupe it took me several weeks to get it right but I haven't changed in since in over 6 months.
