Seems a regular thing this from Bmw and mercede’s taking a deposit and lieing to People about when the car will be ready for handover or exchange.
Maybe this is why they taking deposits and say they won’t order if you don’t. Unless one’s getting added extras then thats down to the dealer and you and nothing to do with MB but any AP should be paid on collection or on the day if it’s a BT not at the point ordering..
I’d be seriously thinking, How long are you prepared to wait with no date and when they often do give a date it’s then a new date and another and another and then 3 months turns into 6 months then into 9 months and maybe more.
Personally I’d speak to Mb get then to spk to the dealer and maybe cancel the order and look at getting something else. Unless it is the car you must have then i guess you will wait but what if in a year from ordering there still no car wait 18 months etc while they hold your deposit and often it’s because your getting £500 off as well and you don’t want to lose that and prices might of also risen since you ordered.
The dealers know this and imo are taking the biscuit….to put it politely
