I've still to register my truck here and hope to get an age related plate,but because i've swayed away from totally stock I might get what's called a 'Q' plate which tells all the world i've got a truck with uncertain parentage!
That's usually the domain of kit cars and one offs.
Good luck with the registration. have you been building the truck to comply with the BIVA test requirements in case the local registration office give you the hard word on an "age related" number plate?
