I heard some time ago of a man who borrowed his mate's Reliant Robin on condition he took it straight to a garage afterwards for it's MOT.
He drove into the garage, called out to the mechanic and asked where to park it and the mechanic said, 'Take it straight in to the service bay, mate.'
This he did and drove it straight onto the inspection pit forgetting it was a three wheeler.
The front wheel went down with an almighty crash and he managed to bring it to a halt just in time. It had more than an MOT by the time the garage was finished with it.
