About the BMW 4 Series Gran Coupe
Launched in 2014, the BMW 4 Series Gran Coupe (F36) served as a stylish four-door alternative to the regular 3 Series, featuring a sloping roofline and frameless doors. The range included efficient diesel engines like the 420d and 430d, plus petrol options from the 420i to the powerful 440i. The second generation (G26) arrived in 2021 with BMW's controversial large grille, updated technology including iDrive 7, and a focus on electrified powertrains including mild-hybrid and plug-in hybrid variants. Standard equipment across generations includes LED headlights, leather upholstery, and comprehensive safety systems.
What Affects the Price
Generation significantly impacts value, with first-generation models (2014-2020) starting from £8,000, whilst second-generation cars (2021 onwards) command £30,000 upwards. Engine choice matters considerably: diesel 420d models offer strong value and economy, whilst petrol 440i and M440i variants attract premium prices. M Sport trim adds £2,000-£4,000 over SE or Sport models due to enhanced styling and equipment. Mileage heavily influences pricing, with sub-30,000-mile examples worth 20-30% more than high-mileage equivalents. Desirable options like the Professional Navigation package, Harman Kardon sound system, and adaptive suspension boost values by 5-10%. Service history is critical; full BMW dealer history adds significant value, particularly for higher-specification models.
Buying Tips
Check the service history meticulously, especially for diesel models which require regular AdBlue top-ups and DPF maintenance. Inspect the run-flat tyres for wear as replacements are expensive; budget £150-£200 per tyre. Verify that all electronic systems function correctly, including iDrive, parking sensors, and adaptive LED headlights which are costly to repair. Examine the frameless windows for correct operation and check door seals for water ingress. For diesel models, ensure the DPF hasn't been removed and that regeneration cycles complete properly. Test the automatic gearbox (ZF 8-speed) for smooth changes without hesitation. Inspect alloy wheels for kerb damage, common on 19-inch and 20-inch M Sport wheels. Check for outstanding finance and verify the V5C matches the seller's identity. For plug-in hybrid 430e models, confirm the battery health and charging equipment is included.
