Our Verdict
A solid option for a premium diesel tourer, provided the service history matches the relatively clean MOT record. The low mileage for a 2018 model makes it an attractive prospect for those seeking a modern 6 Series.
When inspecting this specific 2018 BMW, focus on verifying the service intervals. While the MOT history is relatively clean, the 3.0L diesel engine requires strict adherence to oil change schedules to maintain performance. Ensure that any work related to the single 2023 MOT failure was documented with a receipt.
Negotiate based on the service history rather than the MOT record alone, as the MOT only tests specific safety and environmental parameters. Check for any signs of uneven tyre wear, as tyres are a common failure point for this model type in the wider aggregate data.
As a 3.0L diesel, running costs will be higher than a standard hatchback. You should expect moderate fuel economy suitable for long-distance motorway cruising, but be mindful of the higher tax band and insurance group typically associated with the 6 Series.
Maintenance costs for BMW components can be significant. Budget for premium parts, particularly for braking systems and tyres, which are identified as common failure points in the wider model data. An estimated annual running cost would typically fall in the mid-to-high range for a premium executive vehicle.
Given the aggregate data for this model, pay close attention to the headlamps and tyre condition. The MOT history for this specific vehicle has been largely free of defects since 2024, but you should manually inspect the headlights for any clouding or electrical issues.
Check the brake pads and discs thoroughly. While this vehicle has had no recent brake-related failures, 'service brake excessively' is a top failure reason for this model across the 5,569 vehicles analysed. Additionally, inspect the tyres for tread depth and even wear to ensure they meet safety standards.
This 2018 BMW 6 Series features a 2993cc diesel engine and has covered 47,026 miles as of its last MOT in July 2025. The MOT history shows a consistent pattern of passes, with only one failure recorded in June 2023 at 37,745 miles. The vehicle's mileage is notably lower than the model aggregate average of 8,139 miles per year.
The 6 Series shows an 88.3% average MOT pass rate across 5,569 analysed vehicles, with headlamps, tyres, and brakes being the most frequent failure points.
