Time to get to the dealer is, typically, 3-4 weeks after being built. Your dealer will probably want you to pick a registration number, or he may just asign one to the car, after which he can do all of the registration process "in house", using the online facilities of the DVLA. That bit takes no time at all, so, once the car gets to the dealer, it just needs it's pre delivery inspection (PDI) and valeting. The quality of dealership valeting has been the subject of much discussion, on here, as it is not always as good as it should be. Not a good idea to rush them, as you'll just get a rushed PDI and a poor valeting job. You may even consider taking the car "in the wraps" as I, and a number of folk on here, did, just so that you can make sure the cars initial clean and wax does it justice.
Hope it all goes well and that you enjoy your new car!
