But the question remains, and I invite comments - OK, most of you wouldn't do it to your car - but would you think it cool to see someone else do it, or would you snigger? Would I get invited to display on the club stand at the NEC or would it be unpopular with the club members? (how about I promise to fit boudicca chariot style wheel blades to drive by the 'Fast Ford' club cars?
