Unless things have changed recently Dealers would have the new price lists the week before. I used to work next to the local Ford dealership and our first five Motability cars were Fords and the salesman I used to deal with would always show me the new price list days before. I also had a close friend who was a salesman at the local Audi dealership until a couple of years ago and he told me they had the new prices in the week before.
