OK, Dan-- if & when I get to impound!
I have an couple of e- mails saved somewhere that address the legality of this car. Someone in the SCTA investigated it already and found to their satisfaction that there were more than 500 of this model produced. I'll have other documentation as well, of course.
One thing I've wondered about is how cars in MS can run extended wheelbases since the rule book prohibits lengthening the body. "Removal of minor trim & bumpers is allowed as long as the body is not altered in length, width, or contour."
Maybe this question really belongs in the SCTA Rules Forum, though.
