sorry dude.....I'll try and make up for it
If you are going to put any ID on the car it is probably best to buy a 3dr cossie ID and use that. If say for instance the car you have needed a repair in the floorpan/sill area that just happened to be near the numbers then that could possibly give you an opportunity to put some slam pannel tags from the genuine cossie ID on it and hey presto
As for the Q...they are still doing it according to the DVLA website. There will always be a need to register unknown origin cars to a reg.
If I was you i'd buy a gen cossie ID, repair my rusty sill and rivet the slam pannel tags onto the shell...job done
My bitch slap comment still stands though.....send the Q plate ID off to dvla as scrapped and bin it...its worth fuck all...unless the v5 and the vin numbers match those in the car at present??
