Unless of course if you are a Motability customer, then the vehicle order will automatically be cancelled
the customer will be required to resubmit the vehicle order with the correct vehicle REF for the 85 model otherwise the dealership won’t be able to delivery an 85 vehicle as it won’t match the new 85 REF once they are uploaded to the Motability website.
One caveat is that there is a possibility that the AP will be much higher on the new 85 and some models won’t make it back on;
for example anyone who ordered a 80 sportline RWD after the build week changed they would receive an 85 AWD sportline plus, Motability would never allow this.
Best just to wait and see what the new AP is
