BMW 4 Series (F32/F33/F36)

The first-generation 4 Series was born out of BMW's decision to spin the 3 Series Coupe and Convertible into a distinct model line. It shares its fundamental chassis and powertrain with the F30 3 Series but features a wider track, a lower centre of gravity, and bespoke suspension tuning for a slightly more sporting character. The range is split across the F32 Coupe, F33 Convertible, and the highly successful F36 Gran Coupe. In the UK, the Gran Coupe is particularly sought after as it successfully marries the sleeker roofline of the coupe with the five-door practicality of a hatchback. However, F33 Convertible buyers must carefully inspect the folding metal roof mechanism for smooth operation and ensure the complex drainage channels are clear to prevent water ingress. Mechanically, the 4 Series mirrors the 3 Series' transition from the N-series to the B-series engines around 2016. Buyers should strongly favour the later models to avoid the timing chain risks of the early four-cylinder engines. Check for kerbed alloy wheels, uneven tyre wear, and ensure that the frameless doors drop slightly when opened to protect the window seals.
