Well, I feel like an idiot!
It seems like I jumped the gun MASSIVELY!
So even though I have the registration number for my car, it isn't registered yet! WTF!? How is that even possible??
Dealer says he is just getting everything in place so that once everything is confirmed we are ready to pull the trigger. So even though I know my registration, and have used this info to get 5 days free insurance sorted which starts this Friday....... it isn't registered.
That registration can change at ANY time if someone in any dealer network in the UK picks that registration - unless that particular dealership have reserved those regs and put a notice on their systems that it's not to be used. I wouldn't have activated the insurance at all though until you knew you were picking car up, it may not even be here for Friday.
