Very strong and well made, the large dolly wheels, 2 on each side make moving the car body fairly easy. The height adjustable support pads are handy as well. For me it was an essential item to be able "(with dolly wheels under the front wheels") to move the car out of the garage and turn it around so the rear of the car is now at the front of the garage to enable welding and other work to be done with on the back of the car.
