Looking to get a X3 and one of the ways I was thinking of increasing my choice is to see if I could install an aftermarket hitch (really only to hold a hitch mounted bike rack) instead of getting the factory hitch. IS this kosher on the lease terms (the sales person on the test drive didn’t have a convincing answer).
As long as it’s OE approved or at least you repair any damages made by alteration I don’t see why not as long as the vehicle is returned as purchased less normal wear and tear.
You could also dispose of the vehicle in another manner (sale, trade in for buyout) as long as it makes financial sense to do so (or not, if you like to throw away money, lol.)
