I worked on a couple of hotwheels games, and that was a nightmare for licencing where the car manufacturers go. Cost a lot of money, and were talking toy cars based on real cars. In the end we mostly used made up hotwheels designs with a couple of commercial vehicles. Was really cool that hotwheels made a couple of our designs into actual cars that came with the game.
Fortunately the games sold well over 400,000 copies each within the first two years :)
