Stop in for a cup of coffee

I believe the urethane bumper cars had painted grills. Chrome bumper cars were argent silver

**edit. Looking back at pics from MITP, i see some chrome bumper cars had painted grills too. Never seen a urethan bumper car with silver grill yet.
Your first statement makes sense for a factory’package’ I didn’t even think of the painted bumpers being urethane. But like anything else Mopar, I will never say never. Pretty much anything they did was available ala cart on dealer order.
