Another month for the dealer to do what exactly. To tell you there is no build slot yet and thus no date or info on your order or handover date. How many more months are you to wait without any info on when it will arrive..
You should of called MB a month ago. Other’s seem be having no real issues. It’s clear to me you want that exact car at the AP from jan and want people to tell you to wait forever for it.
Call Mb tell them the issues and get them to contact whoever they have too, to sort out a date for handover or cancel it and get something else. Thats what I’d do.. It’s clear they giving you the run around for what ever reason that’s not your problem. Your not buying the car, MB are and you need to make MB aware of the situation. If the dealer is messing about they need know. Calling the dealer is getting you nowhere?
