@Richard Fountain You can reject the car at any point up until you enter your PIN. In this case call Motability customer service and explain you situation. What would normal happen, if it was the same model and the AP had risen,then you would only pay the AP at the time of ordering.
How ever as this is a new model, replacing an older model,then it is awkward. I think there is an argument that a deal could be negotiated. See what Motability say anyway Richard and take things from there. Let us know how you get on please.
