I see Motability yesterday removed the following passage from their current price list webpage:
Due to uncertainty around the exact arrangements for the UK’s expected departure from the European Union, these prices may be subject to change after 31 October 2019. The prices quoted are guaranteed for cars ordered on or before 31 October 2019 and will apply even if this changes while you are waiting to take delivery of your car (the exception being where the car description is changed subsequent to the original order.)
So, with Brexit currently in a state of postpōnō, I would hazard a guess that the currently listed AP’s would apply for the rest of the current quarter.
