I am in search mode. I think I would prefer a roadster but will likely look at each. We currently have an 09 911 Carrera S and am looking for something a bit more to the muscley side this time. Not that the Porsche does not accelerate well. Love to ad a Turbo S to the fleet but that out of my price range and I believe a Viper will be good bang for the buck. Still leaning toward the 03-06 stuff but if the right car comes along that is newer will definitely look at it. Thanks for the advice and info so far. Hopefully more to come.
The 03-06 Viper's are great cars, the top is far easier to deal with than the earlier R/T10's (which are a mild pain to break down and store).
The later (03 and later) cars have a real, fold down manual convertible top.
The styling is the only issue for me, which is why I still like the earlier cars more.
