I spoke with my dealer last week. He went away and did some checking, including checking if he could pull from stock. My car is due for build and shipping this month. It is expected to be in UK customs on 18th Jan. Then, it will take approximately 2 weeks to clear customs and be ready for delivery, so I’m looking at the end of Jan.
Trying to pay the extra uplift for the relaxation seats, would lead to paying the full new AP, likewise trying to swap the order for something earlier would be the same, so we decided to wait.
