It wouldn't take much to unscrew the chassis off the bottom, remove the interior and glass, and then paint the car any color you want.
Doing this would require making some new decals--in white, black, red and blue. And of course, the interior would need to be painted.
Since I'm also a modelmaker, I can show how to do this. Hmmm....OK, I'll put it into the book (now approaching 200 pages!).
