Fitting your body comfortably into the seat of a Viper coupe (getting in and out) and arriving at a comfy driving position are all key to proper driving ergonomaics. Hefty fellows may wish to reconsider. Also, total height isn't so much a factor as the length of your body's trunk. Guys with long bodies and shorter legs will be tight in the headroom area.
I personally found the shifter to be in an awkward position after settling in. But, that's just me...
You really need to test drive that specific Viper coupe. The process of getting in, driving it and getting out of it will all serve to allow the car to speak to you....Having done that, If you must still ask someone else what they would do, then that specific Viper coupe is probably not for you....
Nearly everyone can be comfy in a truck.... Coupes are a whole nother thing.
