Back in the 80s I had a mate who was building a mini track car and he needed to transport the shell of a mini to another garage. We tied in onto the roof of another mini, so you had a mini on top of a mini, the rope went through the top of the windows so we couldn't open the doors, we had to climb in through the door windows. Nobody seemed to notice, we even drove through Croydon high street, stuff you do when you're a teenager.
