2005 BMW M5 5.0L Petrol · SN55 GTZ

The vehicle’s most recent MOT test, conducted on 18 February 2025 at 73,110 miles, confirms it remains roadworthy with no defects recorded. However, this represents a 15-month gap since the last test, which is beyond the DVSA’s annual requirement. The preceding year’s record reveals a failure in February 2024—specifically for offside front and both rear tyres falling below the 1.6mm legal tread depth—followed by a retest on the same day that passed. This suggests a rushed replacement of tyres rather than a systematic maintenance routine. The pattern of tyre-related failures, particularly in 2023 when both rear tyres were noted as worn close to the legal limit, indicates a history of neglect in monitoring tread depth. The absence of other advisories or defects in recent tests implies the vehicle has not suffered from more serious mechanical issues, but the tyre failures point to inconsistent upkeep. The vehicle’s mileage progression of roughly 3,481 miles per year over its 21-year lifespan is unusually low for its class, particularly given its high-performance nature. Between January 2022 (58,677 miles) and January 2023 (65,057 miles), there was a 6,380-mile gap, followed by another 6,509 miles by February 2024, suggesting periods of inactivity rather than consistent use. The final stretch from February 2024 to February 2025 saw 1,544 miles logged, reinforcing the pattern of sporadic movement. Such low mileage may reduce wear on high-stress components like suspension bushes or drivetrain seals, but it also raises questions about whether the vehicle has been stored improperly, potentially accelerating corrosion or fluid degradation. Given the tyre failures and the lack of other recorded advisories, a buyer should prioritise an inspection of the suspension geometry, particularly the rear alignment and condition of coil springs or bushes, as these are often overlooked in low-mileage vehicles that have been stationary for extended periods. The brakes, while not explicitly flagged in recent tests, warrant scrutiny for uneven wear or binding calipers, especially if the vehicle has experienced uneven tyre wear. Corrosion should be assessed at wheel arches, subframes, and exhaust systems, as prolonged inactivity can accelerate rust formation. Finally, the fluid levels—brake, clutch (if applicable), power steering, and engine oil—should be checked for degradation or contamination, as standing fluids can lose their properties over time. The absence of structural advisories in recent MOTs does not guarantee their absence, so a thorough examination of the chassis and underbody is essential.
