So I'm returning my m235 feb 2020 as the lease is up and thinking about getting into an m340 lease. My question is, if a car is on the lot and doesn't have an option I want, can it be put on after the fact? Like I was thinking of leasing a demo car as the deal is just too good to pass up but since it is a demo car, it will probably be pretty base and I really want the park assist/driver assist feature and the hands free trunk and maybe the wireless charging.
