For those who are unaware, dealers pre reg new vehicles to turn them into second hand units, therefore eliminating a lot of the V.A.T
You get a car effectively no one has preowned at a reduced cost.
I was under the impression that dealers pre-register cars in order to meet new car sales targets and achieve their bonus from the manufacturer.
You'll find a lot more pre-registered cars around when the car market is slow, as it is now.
