My RP31 has an integral 1st gear in it, so I guess that makes it a CM car. Its not lost tho, just in mothballs in the garage. When Gibbie said "Wow, you have an RP31?? thats such a great car. Friend of mine never could beat me until he got one of them. Man what a great car" yeah, makes it hard to part with it. It will be back out someday. Time and economy willing.
