Just an observation from a newbie with 650 miles - I got my car about 6 weeks ago where in PA it was averaging 90+ degrees each day - car felt like it would stick forever on the road - recently we have dipped into the 50's and the roads are getting a bit colder especially in the morning - the car feels ligher regarding its road touch - by this I mean less traction - I can now sense a little better the limits of what to do and not to do in colder weather - I plan to drive my viper through the winter as long as the roads are clean and rock salt levels a non issue. Its simply an outstanding damn car!
