That sort of reclassification after a depature from the approved type is very expensive, worth it if dealing with large numbers of identical vehicles like in your example, but a total nightmare to try and do on a one off basis.
Our country has signed up to all sorts of carbon and emissions based treaties and in order to satisfy our end of the deal we have to be seen to be cracking down on people making depatures from approved specification which may increase carbon emissions etc.
