Selling a registration mark - Mad Maxy
I'm thinking about it... But according to the blurb on a retention certificate I've got, my deal is with the Sec of State, and it isn't transferable to anyone else. Which sounds like 'You've bought it, but once you don't want it it reverts to me, the S of S".

I guess I can sell the mark if it's on a car. Is that the only way I can do it? I feel a call to the DVLA coming on... but can anyone shed a bit of light before I do? (It might help me understand a bit more what they say.)

If its on retension, it can be transfered or sold surely?
