unsure what your budget and requirements are, but strongly consider if a g30 5 series saloon would be a possibility instead, they're not dissimilar money for ~2018 ones, and more of them have xdrive. Plus, they're just better in every single way, build quality, drive, everything (source: I've owned two f36s, a 430i and 440i, and now have an LCI m550i). Also, whilst I thought the boot was big and practical on my 440i gran coupe, the boot is loads bigger on my saloon g30 5 series and it has a remarkably big aperture for loading so you can get pretty much most things that would fit in the 440i.
