Exactly what I had to do when I had my VXR, and it's a damn sight harder to get out of the Zed in my garage. The VXR never had the roof on in the garage so like you say it's a piece of cake to get out of, however I have to park the Zed to one side just to give myself enough room to squeeze out of.
hopefully it will "just" fit in my garage then, can you hop out like in the VXR?
