I say get one too.
I have a couple on my own cars, but have always kept them music related, which is another favorite past time I have. I tried to come up with a few car related plates first, but most were taken already or just unavailable. I'll be working on another one very soon for the 1970 Road Runner, but haven't made up my mind what it'll be yet.
