Query: The worst toy I have ever purchased!!!!!!!!

This is by far the worst toy I have ever purchased. This toy after a lengthy assembly has never one time functioned properly. It is VERY flimsy and constantly falls apart or falls over because it is not structurally sound.Do not waste your money on this toy!!I will never, ever buy another Hot Wheels toy!!!!
