2020 BMW M135I Xdrive Auto 2.0L Petrol · TH52 BEE

The vehicle’s most recent MOT test, conducted on 4 November 2025 at 27,111 miles, confirms full compliance with all roadworthiness criteria—no defects were recorded. This marks the third consecutive annual pass without failings, suggesting the car has been maintained at a baseline standard. However, the absence of advisories or recurring issues does not preclude hidden wear, particularly in high-stress components like suspension bushes or drivetrain synchronisers, which are not routinely inspected under MOT. The clean record from November 2024 (22,478 miles) and November 2022 (15,808 miles) implies no major mechanical trends, though the single fault in November 2023—a near-side rear tyre with cracking—indicates at least one instance of neglect. Without further context, this could reflect a one-off oversight rather than a systemic pattern, but it warrants scrutiny of tyre history and potential uneven loading. The recorded mileage of 27,111 miles over five years (as of July 2026) averages approximately 4,518 miles annually, a figure significantly lower than the UK average for a vehicle of this age. The gaps between tests—consistently around 3,500 to 4,000 miles—suggest the car has been stored or used sparingly, which may mitigate some wear but also risks fluid degradation (e.g., brake fluid, coolant) or component dry-rotting. The most notable mileage jump occurred between November 2022 (15,808 miles) and November 2023 (18,966 miles), a 3,158-mile increase in a year, though this remains within reasonable bounds. The lack of advisories in recent tests implies no urgent servicing was deferred, but prolonged low usage could mask issues like seized suspension joints or degraded hoses. A buyer should prioritise an independent inspection of the suspension geometry, particularly the rear subframe and bushings, given the tyre fault in 2023 and the car’s high-performance nature. Binding or uneven brake calipers—common in BMWs with aggressive driving—should be checked, alongside fluid levels and condition. The drivetrain, including the automatic transmission and differential, should be assessed for fluid leaks or unusual noise, especially if the car was ever driven aggressively. Corrosion in wheel arches or underbody panels, while not yet flagged, is a risk given the vehicle’s age; close attention to the near-side rear area is advised. Finally, verify the service history for timing belt (if applicable), carbon build-up on intake valves, and spark plug intervals, as these are often overlooked in low-mileage cars.
