Coupe. Just to offer a different perspective. Personally, I hate open air driving(yes...I've driven a RT-10 and other verts). To me it is very distracting when driving at high speeds. Predominate weather conditions probably influence me too as here in Dallas(102 today) it's just too d a m n hot most of the time. Additionally, I don't like all the open air noise(wind and traffic), exposure to bird $hit and road debris and lack of roll over protection(even have an Autoform rollbar in my GTS). I also prefer the looks and stronger chassis of a Coupe. However, as others have stated it's what you like and prefer. Both Vipers are great! Good luck with your decision and post some pics of the new Snake.
