I have just put a number on retention.you have to retain number first or it will go to new owner.
DVLA issue the old number online straight away.You download a document which you take to number plate supplier with old V5 .you only have 7 days from issue to transfer.
Then the new buyer can change address.
Make sure you fill your part of V5 in and post it off.
Alot of garages say they will do,it so another keeper doesn't appear but id any speeding or parking tickets are clocked up you will get them arriving at your door !
I know someone who moved after part ex car 12 months later baliff turned up for unpaid fines the new keeper never changed address.
Also taxing at the right date or you can be charge for the full month as tax is not transferable now.
