1986 BMW 6 SERIES 3.4 635csi

The BMW 6 Series, a luxurious grand tourer available as a coupé, convertible, and later a four-door Gran Coupé, has graced UK roads across several generations. Known for its elegant styling, powerful engines, and a sophisticated blend of comfort and performance, it appeals to discerning drivers seeking a premium, long-distance cruiser with undeniable road presence.

Why Buy a Used BMW 6 Series?

• Sophisticated design: The 6 Series, especially the F06/F12/F13 generations, offers timeless aesthetics that still turn heads, providing a premium feel without a new car price tag.
• Powerful and refined engines: With a range of smooth, potent petrol and diesel engines, the 6 Series delivers effortless performance whether cruising or accelerating, making long journeys a pleasure.
• Luxurious and well-appointed interior: Expect high-quality materials, advanced technology (for its age), and comfortable seating across all variants, providing a truly upscale driving experience.
• Grand touring capabilities: Designed for eating up motorway miles, it excels in comfort and stability, making it an ideal choice for those who value long-distance cruising.

Typical Price Range

All prices are approximate and subject to change based on condition, mileage, specification, and market conditions.

• 2010–2014: £9,000 – £18,000 — Earlier examples of the F12/F13/F06 generation, offering great value for money for a luxury GT. Check service history rigorously.
• 2015–2018: £18,000 – £30,000 — Mid-life models, often with desirable upgrades and lower mileage. A sweet spot for many buyers balancing age and features.

Common Issues to Check

• iDrive system glitches: Older models can suffer from software bugs or failing screens. Ensure all infotainment functions work correctly during your test drive.
• Electrics and sensors: BMWs, particularly older ones, can be prone to various electrical gremlins, including parking sensor failures or window mechanism issues. A full diagnostic scan is recommended.
• Tyre wear: Due to the car's weight and power, especially on M Sport models with larger alloys, tyre wear can be accelerated. Check the condition of all four tyres carefully.
• Suspension components: Bushings, linkages, and adaptive suspension components can wear over time, leading to knocking noises or a less composed ride. Listen for unusual noises over bumps.
• Diesel particulate filter (DPF) issues: On diesel models, particularly if used primarily for short journeys, the DPF can clog, leading to costly repairs. Check for appropriate regeneration cycles in the service history.

Running Costs

• Fuel Economy: 30 – 50 mpg (depending on engine and driving style, diesel models typically higher)
• Insurance Group: Group 35 – 50 (varies significantly by engine, trim, and specification)
• Servicing: Main dealer servicing can be pricey, but independent BMW specialists offer competitive rates. Look for comprehensive service history with any used purchase to ensure preventative maintenance has been carried out. An annual MOT will also be a recurring cost.

Which Variant Should I Choose?

• 640d Gran Coupé (F06): Perfect for high-mileage drivers who desire a blend of executive luxury, strong performance, and reasonable fuel economy. Its four-door coupé styling is particularly attractive.
• 650i Convertible (F12): Ideal for enthusiasts seeking exhilarating V8 power and the joy of open-top motoring. It’s a less practical but immensely rewarding choice for weekend drives and fair-weather cruising.
• 630i Gran Turismo (G32): Suits families or those needing more practicality than a traditional coupé, offering a spacious cabin and a large boot. It combines hatchback versatility with executive comfort and modern BMW technology.
• 640i Coupé (F13): A great all-rounder for those wanting strong performance from a smooth petrol engine without the higher running costs of the V8. The classic coupé silhouette is timeless and appealing.
