Go-Jak 6313
These really are a great way to move a car around. The foot jacks work well and lift each tire easily. You do have to put some effort into getting the wheels on all 4 Go-Jaks pointing the same way, but once it starts moving in the right direction, it's very easy to move. Letting them down off the jacks is as easy as flipping a lever and using the foot handle again. These are worth the money if you'll be moving cars even only every once in a while.
