I thought wheel dollies would help move the two outboard cars closer to the garage wall. That way I don't have to try and drive the cars close to the wall. Plus, getting out of the driver's side on the far left car would be a bear, as it's driver's door is up against the wall. I figured I'd drive a car into the middle of the garage, put it on wheel dollies, and push it up against the wall. Only the two outboard cars would be on dollies. Of course, like you mentioned, the car in the middle has to come out whenever I want one of the two outboard cars removed.
