I signed on the 22nd June. Spoke to dealer this morning, and he said no problem, they will change the price when they know the actual pricing.
I had already optioned the Air Suspension, Lights and Area View, so he expects my price to come down. As such I have now added the Dynaudio which means the car is now fully loaded except for the 4xMotion, which I do not need.
The dealer said the basic price may increase a small amount but I will certainly have money coming back to me, even after adding the Dynaudio.
I am more than happy with the deal I finally got, it also got the Corporate Plus Discount.
