Oh no Vlad, the dealer has been bluffing you since the beginning I read on your previous thread when you ordered. I believe you also had half price on the HK sound system which you missed out on. Re-check your order paperwork, the live cockpit plus and screen is only 8.8″ touch display (attachment below) compared to the larger one you get on the M Sport.
Also, Wayne is correct, perhaps your dealer ordered before July or you mentioned your dealer said he had another in stock?? These things do tend to update. Good luck chasing it up with Motability as looking at some member’s experiences they sometimes can’t assist. Must be really frustrating for you.
