I’d say only Mb can answer that question, as each person’s case is different, it would be them that decides if you can place another order if you cancel one you’ve placed.
I guess they wouldn’t want to leave you without a car, but there are limtations to that and by cancelling an order they may deem that in a way that means you break the terms of the contract with them.
As your over the 5 years extention period, under that you could be sure that it’s ok to do it.. although personally I would not order myself and plan to cancel that order once i’ve placed it or advise anyone to do so…
They might be able to source the car quicker as you not bound by the 3 month order wait time. Which means you got another set of problems to consider.
I have had suv’s and mpvs on the scheme but last 2 have been cars and i do find all have problems for me getting in or out of but what it does is increase my options, as i cannot afford huge ap’s and car needs to meet my needs. Once i’m in that’s what really matters.
