It just takes 3 pieces of square (and free) vinyl to change the color of any car to whatever you like.

Lambo-green Enzo? No problem. Any other color than orange for a M3? Go ahead.

Just go to 'customize', 'Vinyls', select 'Basic', add a square in the center part of the car and press the 'Paint through' button at the top end of the screen. Select the desired color. Enlarge the square and confirm. Repeat this for the front side of the car and the rear.

Nice new bonus feature to get rid of the colors you allways hated without even having to pay for it!

Update:

It is even more easy than i first suggested. Before applying any vinyls: rotate the car so you look at the front. It only takes one square (and free) vinyl to do the job....

Another Update:

Most cars look much better with the original vinyls removed, i.e. the Hyundai in full black looks way cool!
