I am (was) in the process of a NASCAR dio myself.
Restrictor Plate Racing was the working title with Bill Elliott and Dale Earnhardt "flying" along the wall at Talledega. I even had Kyle Petty in the mix.
I found the idea on the cover of RACER magazine, which I had planned to put near the dio.
I realized though I needed Drivers for the cars! (Duh), I'm not sure I want to shell out $$$ for the new kits just for the drivers.

I know it's only rock and roll, but I like it.
