A neighbour of my parents used to be in the executive end of the used car business.
He would buy at auction old bangers for the number plate.
In order to transfer the number plate from the old banger to the nice new Roller, the old banger needed an MOT.
As he ran the garage, that was easy to arrange, so no matter what condition the old banger was in, it had a new MOT
They then swapped the plates, old banger plates to new Roller, new Roller plates to old banger.
Flog the new Roller with 'Cherished Plates' for loadsofmoney
Then my brother and I would buy the old banger for the normal price of two bottles of whisky
12 months MOT and the plate of a Roller, so no one is going to pull you over from any evidence on the PNC cameras.
Some of the bangers were great, others not so, at one time I think we had three of them, the one we were using and a couple of spares, as you never quite knew when you would need to abandon yet another one on the side of the road.
It kept us in cars for a number of years, some of the memorable ones were a bubble car, a couple of mini's, at least three Morris 1000's, a Ford Prefect, a couple of VW Variants, a VW camper van, an MBG GT, several Ford Escorts and many others that I forget.
Some of the cars we sold on, one of the Variants was turned into a fake fibreglass Porch 911, and one of the Escorts was sold to a guy who had a company Ford Escort, the company had made him redundant on a Friday, so over the space of the weekend he swapped over the engine, the wheels, the seats and as much else as he could, so the company got back their car on Monday but with a engine with an extra 200,000 miles on the clock, worn tyres, trashed seats etc.
