Hi and welcome.
is you new B-max an automatic?
If so, I suggest you take it for a good run and check is all well with the clutch/gearbox, and there are no 'Judders', as there has been an ongoing problem with them that Ford know about. (see previous posts)
I had a new clutch fitted to mine because of this, and all is now well.
Hope you will have a good experience with your B Max, mine I bought it new in 2016 Titanium version 100bhp Ecboost and I still love like the first day. Never had a Ford before and I was a little bit worried but now I don't regret my decision.It's so easy to drive and after 27000km not any single issue.
