It’s a tuff situation for you carl and i feel for you, it’s funny how when something falls through the cracks of the system these unsolvable problems occur of which none are your fault. It just adds more stress to our livesand sometime we just cannot handle it all..
It maybe worth getting onto Mb again with the situation and go higher up there also.
I had issues before and it was sorted by the big wigs as it was far from a normal situation that anyone on the phones could handle.. This sounds like one of those.. Mb need to speak to the dealer and if the car was ordered and not put into the system they should honor the AP of when you ordered. After all you pay the ap at the time of ordering and the dealer is the broker between you and mb.
As glos guy says you got a hard choice to be made if it cannot be resolved and i personally would feel cheated if i had to pay more than the original ap because of the situation and or order a new car and wait again, what if you don’t have more funds what then… some of us are on low incomes and save up for the ap and it’s hard to find that extra out the blue also.. So thats another issue as well.. as well as if you did look for a different car you canot test drive any right now due to lockdown.
