tinytim, the question why you are unable or unwilling to collect the car from the dealer has been asked a number of times and remains unanswered. Of course you don’t have to answer, but without any explanation it seems to me that you are taking a stand on the principal of a broken agreement that Motability said you could have off site delivery and now refuse, and that their action is illegal. In taking that stand, you are willing to go without the car.
If all that is the case, I don’t see what further discussion here can achieve.
