Actually, I have seen on another forum that someone who had an order in for a Q4 Sport 40 on 21/08 to be delivered around Christmas and with an AP of £5,999, has had this changed to a Sport 45, same delivery date, with an AP of £4,999 (i.e. £500 more than the current AP for a Sport 40, but £1,000 less than the AP pre-October 1st. This is for real as he has received new paperwork from Motability to that effect.
So I’m guessing that, maybe (only maybe!), the Sport 40s will stay on the list at £4,499 to clear off Audi’s current UK stocks (about 20 or so according to the Audi UK website) and the Sport 45s will be introduced alongside them at £4,999. They also have about the same number of Sport 35s in stock so I wonder if Audi might try and sell them through Motability at a reduced AP also??
