I agree with letting the kids twist on the steering wheel also. Young smiles are what it is all about. BUT, I don't have a concourse car and I didn't spend the last 10 years restoring it these guys have a right to say look but don't touch. My cars are both 20 year old restorations with very nice paint. 5 footers at best and both are driven regularly. I would hate to see them scratched by a baby carriage or a belt buckle but dirty sneakers on the seat is no big deal.
