Got it, cheers BigDave. They we’re charging me for the wrong model!
In your favour or theirs??
Have you logged into the Motability website and checked in your account that the correct vehicle with the correct AP is shown there?
It might be worth speaking with Motability when they re-open tomorrow if the dealership cannot easily resolve the matter to your satisfaction.
If anything needs changing make sure the dealership do not try to charge the Q1 2022 AP (if it is more expensive than when you placed the order).
