Congratulations neenee on your beautiful new car.
Great spec have you taken any photos yet?
As Zack said 18 miles is to be expected on the delivery, mine was 16.
The illuminated visor I cant advise sorry but Im sure Jon wont be long
If they missed the crome internals then I would use that as a negociating point for the roof programming.Key opening is not standard ...Sorry
With some sweet talking you should be able to get them to do the re mapping (computer adjustment for the roof) at least reducced ££
The seats I would deffinatly keep on at them about.
The crome should not take long to come in, give them a phone and ask how long they will be and ask about the seats again.
Good luck, but most of all enjoy your new car
