Any advice on how I could build a heavy duty sliding track that would allow a car to be driven on to it and then pushed/pulled along?

Story behind this is that my garage is extremely narrow, it fits my car in but there's no way of getting out of the car when it's inside. It's also terrifying to drive it in there.If I can build a track that the car can be driven on to and then push the car along in to the garage for storage. It's a classic car hence wanting to store it. Then the same in reverse, the car can be pulled along the track out of the garage and reversed off it again.Borderline insane I know, but any suggestions? via /r/DIY http://ift.tt/2orzWDA
