There are certain ways to customize your car - paint, rims, window tinting, etc., but covering your ride in toy cars is certainly a new kind of customization.
The General Carbuncle is a car covered in 4,342 toy cars and is patterned to resemble the General Lee, with the flag on top and number 1 on the side. The design is definitely an interesting use of toy cars, though I would fear they would all fly off on the highway!
