What the reviews say

• This 6 Series is a comfortable grand tourer: quiet and assured on motorways, with an acceptable ride even on 20-inch wheels.[1][3][4][5]F06/F12/F13
• Steering is precise and braking is strong, but its size and weight are noticeable; it is less agile in town than a smaller sports car.[1][2][5]F06/F12/F13
• The high-quality cabin is driver-focused and roomy up front, while the low roofline limits rear-seat space.[1][4][6]F06/F12/F13
• The Gran Coupé adds useful practicality with four doors, a good boot and folding rear seats, though the centre rear seat is very narrow.[1][3]F06/F12/F13

Typical faults

• The petrol N55 has reported turbo trouble and oil consumption; one car at 256,000 km had a stretched chain and broken guides that left metal debris in the oil.[1][5]F06/F12/F13

  256 000–256 000 km · N55

• One 640d at 140,000 km had failed engine mounts causing strong vibration, plus a leaking seal on a turbo pipe.[5]one sourceF06/F12/F13

  140 000–140 000 km · N57

• Front suspension parts may crunch or bind, while anti-roll-bar bushes can squeak in wet weather; one car required replacement of a component and the bushes.[5]one sourceF06/F12/F13
• The front side-camera contacts can oxidise, while the retractable rear camera may stick open; dismantling and cleaning restored them on one car.[6]one sourceF06/F12/F13
• A Riga workshop documented diagnosing a parasitic current drain and selecting a Keyless Go repair solution on a BMW 640 F12/F13.[8]one sourceF06/F12/F13

Which engine and version to take

• The 3.0-litre 640d is the strongest choice: sources describe the N57 as reliable, muscular and well suited to this heavy grand tourer.[1][4][7]F06/F12/F13
• The N55-powered 640i is smooth and powerful, but its turbo, oil consumption and timing-chain condition deserve particular scrutiny.[1][3][5]F06/F12/F13

What to check at the inspection

• Demand a complete service history and favour an unmodified car; for the 640d, one source advises oil and filter changes every 8,000–10,000 miles.[1]one sourceF06/F12/F13
• Check for proof of automatic-transmission servicing; one source recommends doing it at 80,000–90,000 miles.[1]one sourceF06/F12/F13
• Look for smoke on a cold start and check oil consumption; on an N55, inspect the oil filter for metal debris and establish the timing-chain repair history.[1][2][5]F06/F12/F13
• Start a 640d from cold and check for vibration, failed engine mounts and oil leaks around the turbo pipes.[5]one sourceF06/F12/F13
• Test Keyless Go and every camera, confirm the rear camera extends and retracts, and measure the battery's parasitic draw.[6][8]F06/F12/F13
• During the test drive, listen for front-end crunching and squeaks over bumps, especially in wet weather, and inspect the anti-roll-bar bushes.[5]one sourceF06/F12/F13
