2023 BMW M135I Xdrive Auto 1.5L Petrol · J7 XCE

The vehicle’s most recent MOT, conducted on November 8, 2025 , at 15,743 miles , passed without major faults, though it carried two minor advisories: the nearside front tyre was worn dangerously close to the legal limit (2mm tread remaining) and exhibited uneven wear on the edge, while the nearside rear tyre showed signs of cracking or perishing. This represents a stable maintenance trend over the past three tests, with no recurring serious defects. The absence of failings in the 2024 and 2023 tests suggests the vehicle has been kept in a state of basic roadworthiness, though the advisories indicate deferred attention to tyres—a critical component for safety and handling. The recorded mileage of 15,743 miles over three years —approximately 5,248 miles annually —is unusually low for a vehicle of this age and specification, particularly given the M135i’s performance-oriented nature. This pattern implies either very light usage or prolonged periods of inactivity, which could accelerate wear on fluids, seals, and suspension components. The gap between tests (around 12,000 miles per cycle) aligns with standard MOT intervals, but the lack of intermediate servicing records raises questions about whether routine maintenance—such as brake fluid changes, differential servicing, or suspension inspections—has been consistently performed. A prospective buyer should prioritise an independent inspection of the tyres , particularly the nearside rear, to confirm the extent of perishing and whether the front tyre’s edge wear has progressed since the MOT. The absence of brake-related advisories in recent tests is encouraging, but the rear brakes should be checked for binding or uneven pad wear, given the vehicle’s performance bias. Additionally, the suspension bushes and coil springs warrant scrutiny for premature degradation, as low mileage does not guarantee their longevity—especially if the car has been stored without movement. Finally, the exhaust system and underbody corrosion should be inspected, as these are often overlooked in low-mileage vehicles but can develop silently over time.
