M Sport trim is extremely popular and the one we’d go for. It comes with 19in wheels (18in on the 530e), a sportier bodykit, black rather than chrome exterior trim, sport seats, an M sports steering wheel, a black headlining and an instrument panel wrapped in faux leather (or as BMW puts it, synthetic leather). Just make sure, however, that if you do go for M Sport you also tick the box for the optional M Sport Pro Pack. Amongst a plethora of other goodies, this introduces adaptive suspension (on all models aside from the ‘entry-level’ 520d and 520i) and gives the 5 Series a plush ride.
