I'm looking at purchasing a new car outright from an online broker. They inform me that I will be the registered first keeper, although the VC5 will be in my name (care of) and the address will be that of the broker. I understand they do a lot of car leases so this is how they negotiate discounts.

Once the car is delivered to me they will request the address be changed to mine. I've read a lot about firms pre-registering cars so although you are buying a new car you are still the second registered keeper, but I've not come across this mechanism before. Is it legal to register the car in my name but the address of the fleet company and then transfer it?
