Gary's workshop is overflowing with automotive parts waiting to be sorted and assembled into something that actually runs. Players must sift through the clutter, identify which components belong together, and use creative problem-solving to construct a functioning vehicle—whether a speedy roadster, a sturdy truck, a practical sedan, or a competitive race car. Gary offers occasional guidance but leaves most of the puzzle-solving to the player, encouraging them to experiment and learn how different parts contribute to a car's performance and purpose. The challenge deepens as players realize that different vehicles demand different specifications; a machine built to tackle steep inclines requires sturdier components than one designed for casual city driving. Once a vehicle is complete, players can access additional parts online to customize and enhance their creation.
