What your profile looks like.
The Car Profile was a feature in The World of Cars Online.
It shows everything: your paints, your costumes, and all kinds of other gear. It also shows what your car looks like, your racing points, car name, D-Name, badges, and even souvenirs. You coul use this to customize your car and view all of your belongings on the game.
If you clicked another player's Car-Profile you only could see his current look, collectibles and souvenirs, and there was a Friend request button to add him as a friend.
