I like the decal idea just as long as it isn't too big and gaudy. Something simple, clean, and Red. You could have them in the different shades of red to match the cars even closer. I'll take a laser red one now!lol Have you ever seen the Mustang week logo. It's clean and simple. I'm not saying ya steal there design just use it as a reference when designing the RMC one.
Also my status now staits "Red Mustang Club will own all!"
