About the BMW 4 Series
Introduced in 2013 as a two-door spin-off from the 3 Series, the BMW 4 Series is available as a coupé, convertible, and Gran Coupé four-door. The first generation (F32/F33/F36) ran until 2020, featuring engines from the 420i four-cylinder petrol to the 435d six-cylinder diesel, plus the high-performance M4. The second generation (G22/G23) launched in 2020 with a controversial larger grille, updated technology, and mild-hybrid powertrains. Standard equipment includes leather upholstery, iDrive infotainment, and comprehensive safety systems, with M Sport trim being highly sought after.
What Affects the Price of a Used BMW 4 Series
Age and mileage are primary factors, with 2014-2016 models starting around £10,000-£15,000, whilst 2019-2020 examples command £25,000-£35,000. Engine choice significantly impacts value: four-cylinder 420i and 420d models are most affordable, six-cylinder 430d and 440i versions add £2,000-£5,000, and M4 models start from £30,000. Trim level matters considerably, with M Sport commanding a £2,000-£3,000 premium over SE models. Convertibles typically cost £3,000-£5,000 more than equivalent coupés. Full BMW service history can add 10-15% to value, whilst accident damage or incomplete history significantly reduces prices. Optional extras like adaptive suspension, Harman Kardon audio, and head-up displays add desirability.
Tips for Buying a Used BMW 4 Series
Check for complete BMW service history, particularly timing chain replacement on N20 four-cylinder engines around 60,000-80,000 miles. Inspect the condition of run-flat tyres, which are expensive to replace, and verify all electronic systems function correctly, including iDrive, parking sensors, and adaptive headlights. Examine the soft-top mechanism thoroughly on convertibles for leaks and operation speed. Check for excessive tyre wear on the inside edges, indicating suspension issues common on lowered M Sport models. Verify any M4 has documented evidence of previous maintenance given the high-performance nature. Test drive for smooth gearbox operation, especially on eight-speed automatics, and listen for turbocharger noises on diesels. Consider approved used BMW schemes offering extended warranties for newer models.
