The name of the game is to customize your car. You can choose which car would be your car and from then on, you can do some customization so that it would turn out like the one that you like.
The game is played with a mouse. You can do whatever you like with the car. As long as you like the outcome then it is the best design. Don’t let others tell you what to do as you in control of the game. Everyone has their own preference so try to be original and not like the others that seem to depend on the car manufacturing for their own car design.
