About the BMW 6 Series
The BMW 6 Series has been produced across three generations since 2003, with the E63/E64 (2003-2010), F12/F13/F06 (2011-2018), and G32 Gran Turismo (2017-2020) models. The range includes straight-six and V8 petrol engines, plus diesel options from 2012 onwards. The F-generation introduced the four-door Gran Coupé bodystyle in 2012, expanding the model's appeal. Performance variants include the M6 with its 4.4-litre twin-turbo V8 producing up to 600bhp in Competition spec. Standard features across the range include leather upholstery, professional navigation, and advanced driver assistance systems on later models.
What Affects the Price
Generation and age significantly impact values, with E63/E64 models from £8,000-£18,000, F-generation cars from £15,000-£45,000, and recent G32 Gran Turismo models commanding £35,000-£55,000. Mileage is critical—cars under 50,000 miles attract premiums of 20-30% over higher-mileage examples. Engine choice matters considerably, with 640d diesels offering strong residuals due to economy and performance, whilst M6 models hold value well due to rarity. Bodystyle affects pricing, with Gran Coupés typically £2,000-£5,000 more than equivalent coupés. Full BMW service history adds 10-15% to value, while cherished options like head-up display, B&O sound systems, and individual paint colours increase desirability.
Buying Tips
Insist on comprehensive service history, particularly evidence of oil changes every 10,000 miles or annually. Check for electronic issues including iDrive faults, parking sensor failures, and dashboard warning lights—common on higher-mileage examples. Inspect for oil leaks from valve cover gaskets and oil filter housing gaskets on V8 engines. Test the convertible roof mechanism thoroughly on E64 and F12 models, as repairs cost £1,500-£3,000. Examine alloy wheels for kerb damage and brake discs for wear—replacements are expensive at £800-£1,200 per axle. Verify the gearbox shifts smoothly, particularly on 630i and 640i models where torque converter issues can arise. Budget £800-£1,500 annually for maintenance and check insurance group ratings (typically 45-50) before purchasing. Consider approved used schemes from BMW dealers which provide warranties and thorough inspections.
