I really don't think the fact that the mustang was intoduced in 65 vs 67 for the camaro had a whole lot to do with Mustangs outselling camaros in the late 90s. I do know what its like to try to drive a RWD car in the snow... and even spun a 1990 454SS around once to prove its not a good idea to drive one between November and April around here...
