Some of these are too funny, Ricky Bobby, Al Bundy, Ricardo Montalban, Snidely Whiplash!
Now I'm torn. Ricky Bobby and Todd made me laugh the most, and I was sold on Al Bundy for a minute there.
If it was a Charger I could sign it Crazy Larry, or a Challenger Kowalski.
If you want something more serious, try this. Back in the day, Chrysler sponsored a Barracuda in TransAm, driven by Scott Harvey. Put his autograph on the glove box lid. The link is to a picture of the 66 car. Sorry, no photo of the '67
The problem with using someone's name from '60s or '70s racing is they are probably still alive, and forging their name would be disrespectful. I say use a name from a movie or a cartoon that fits the car.
