About the BMW 6 Series Gran Coupe
Launched in 2012 and produced until 2018, the 6 Series Gran Coupe offered a stylish alternative to the traditional 5 Series saloon. Built on the same platform as the 5 Series but with a longer wheelbase and lower roofline, it featured frameless doors and a four-seat or five-seat configuration. Engine options included the 640i and 640d, along with the performance-focused 650i and M6. Standard equipment was generous, with leather upholstery, Professional navigation, and advanced driver assistance systems. The Gran Coupe competed with the Audi A7 Sportback and Mercedes-Benz CLS, offering distinctive BMW driving dynamics wrapped in an elegant body.
What Affects the Price
Model year significantly impacts value, with pre-facelift cars (2012-2015) starting from £8,000, whilst facelifted models (2015-2018) command £20,000 upwards. Engine choice matters considerably—the popular 640d diesel represents the sweet spot for value and running costs, whilst petrol 640i models tend to be cheaper to buy but costlier to run. The M6 Gran Coupe commands premium prices due to its 560bhp V8 and rarity. Mileage is crucial, with sub-30,000-mile examples fetching significantly more than those over 80,000 miles. Specification level affects desirability—cars with the M Sport package, adaptive LED headlights, and Harman Kardon audio hold value better. Full BMW service history is essential for maintaining value, as is condition of the interior leather and the expensive run-flat tyres.
Buying Tips
Inspect the service history meticulously—BMW main dealer stamping is preferred, but specialist servicing is acceptable if comprehensive. Check for oil leaks from the engine and gearbox, particularly on higher-mileage V8 models. The automatic gearbox should shift smoothly without hesitation or jerking. Examine all four alloy wheels for kerbing damage, as replacements are expensive. Test all electronic systems including the iDrive controller, head-up display, and parking sensors, as faults can be costly to rectify. Look for uneven tyre wear indicating suspension or alignment issues. Verify the exhaust system for corrosion, especially on 640d models. Budget for annual running costs including expensive tyres, premium fuel for petrol models, and potentially high insurance premiums. Consider an independent pre-purchase inspection, particularly for M6 models where engine and drivetrain repairs can exceed £5,000.
