Are DVLA are creating a problem for themselves here? Mate has a small manufacturer's confirmation of build for his car but DVLA refuse to accept it, stating they need Glass's data as proof. Since this is a specialist car, it never appeared in Glass's guide. But how on earth can you beat the manufacturers own data, anyway? I think they will find themselves in some hot water shortly, as this is neither reasonable, nor defendable.
Trouble is as a Government monopoly they can shift ground and then call this a non production car and turn it into a Q plate or some such. In this way they can undermine a lot of interesting cars freedom to use the roads, which are currently taken for granted. Not least as the insurers follow the lead of registrations and oddball registration marks mean higher risk to them. Q plates being a case in point. Having set a precedent, what other manufacturers information is going to be ignored, in favour of some non technical middleman entity, that does not have all the answers. Will existing large manufacturers word be taken, but no one else's, creating a two tear system. This style of corporate fascism means dangerous times for the freedom to be doing what you want, or paying extra for it. Well what a surprise if that is so!
Already I see dodgy ploppers being sold as road going cars on eBay. This MOT free thing might look great, but it is very much a double edged sword. As usual the geezers will go for cash gains and it might end up blowing up in our face. Yet DVLA is very keen to cut its administration costs as it has really given up any pretense of being a service to the public, and is primarily an arm of information collection for taxation and fee purposes to enrich the Government coffers. So if the complaints come in of rampant malpractice in sales of substandard pre '60's cars do not expect any quarter for the enthusiasts who are doing it right.
