basically i've just sold the saff, and it's going tomorrow....but it came totally out of the blue and was not planned at all.

my private plate is on the car but i don't have a clue how to go about keeping it

the V5 will be filled in tomorrow obviously and then i guess technically the plate belons to the new owner? he's agreed to give it me back, but is it as simple as filling out forms and paying a fee.....or is it gonna be difficult once the car is registered to somebody else?

please help
