There is nothing cheap about buying a low cost dolly that could cause you to damage your car.
Damage ? ... how so ??
When you push the car and the casters don't pivot correctly and your car hits the wall or even worse another car.
So which is it, are they too hard to push, or do they roll too easily? With mine at least, you push the car into something it's your fault because the things won't roll on their own on a flat floor.
You need to pay attention to what's going on, and not use them on an incline. In other words, use your head for something beside a place to store a hat.
