The copied a-chassis vehicle dont work, the suspension and the vehicle itself

Hello, I was making a vehicle with A-chassis and finally i finished it, i scripted a press f to enter vehicle and i copied the vehicle to put in the side of the another one, to test if it was working, when i entered the copied vehicle, it wont move and i dont have any idea why, something i noticed it was weird is that the suspension color was red instead of black, even if in the script i put it to be black

any help is appreciated, thanks for the attention!
