I'm a bad person. I've had my age related registration number, for my CL450, for all of three hours, when the post came, and I'm looking into the legality of selling it, and whether DVLA would then give me another (non transferable) age related number for my bike, or tell me to do one for being such an ungrateful money grabbing bar steward.
This one doesn't say 'non transferable' on the V5, but the number ends in '912 H'. Classic Porsche 912 (4 cylinder little brother of the 911) owners are a pretty well heeled bunch, and someone with a 1969 one would pay good money for the plate - '911' numbers are occasionally advertised for ridiculous money in my classic car porn mags. You couldn't put the plate on an older 912 as you can't make a vehicle seem younger than it really is, and 1969 was the last year of 912 production, apart from the 912E in 1976.
Perhaps I should bide my time and do the odd classic show, and wait for an offer I can't refuse....
