about the only thing we don’t like about our X1 is the non adjustable seatbelt hangers (Jeremy Clarkson doesn’t like them either!) the standard seats (2017 model) for us are fine they are firm but BMW have always tended to be on the firm side. Smallest wheels would be best as the larger optional wheels are a bit rough around the country lanes. 1.8d s drive gives over 50 mpg all round and mid to high fifties on a run
