Ms Skunksyard/RE: Cars
Advertising is big business on the NASCAR Circuit. It is also popular and gets attention in other series as well. NASCAR, if you are running near the top, the companies that pay for the big spots on the cars get plenty of exposure. Think of Mark Martin, You think of the #6 Viagra car. Think of the late great Dale Earnhardt, You thing of the #3 car as GM Goodwrench. Yes, racing fans are loyal to the branding on their favorite driver. It is a win, win situation for the team and sponsor alike.
