Welcome to the forum, my advise is find out which dealer is giving the best Mobility deals, on the car/cars you are interested in. Test drive, choose any extras for want/need and order right away. Check that any further AP drops will be adjusted to you.
Piece of mind that you have your order in and on the system and you are covered. That’s what I did last week.
