Go to the Kudos World Challenge. Next go to the the car select screen. Then to your garage. Once inside your garage, press Y to walk around freely. Walk over the the arcade machine and press A. This will allow you to play the arcade game Geometry Wars.

While logged onto XBox Live, in the room, pick any color car you want outside of the class of cars you want. Then you exit out of the game and go to single player and go onto ghost challenge, pick any race and then pick the car you want.
Just highlight it and then when it ask for automatic or manual transmission, back out of there and go back to the room. You will now have the color car you want on your favorite car.

When you go to your garage, look at the corner with the toolboxes and tires, and there should be an arcade game named "Geometry Wars". If you hit the A button, then you can play it.
