2000 BMW M5 4.9L Petrol · X891 BND

The most recent MOT, carried out on 11 July 2025, was passed with no recorded defects, and the preceding three annual tests (2024, 2023 and early 2022) also returned clean passes. This uninterrupted sequence of defect‑free results suggests a stable maintenance regime and that any routine servicing required to keep the car roadworthy has been performed consistently. There is no indication of a deteriorating trend, which is a positive sign for a vehicle of this age. At 135,743 miles recorded on a 2000‑model BMW M5, the average annual mileage works out at roughly 5,200 miles per year, considerably below the typical UK usage pattern for a performance saloon. Such low utilisation often points to periods of limited use or extended storage, which can be as consequential as high mileage. While the reduced wear on engine, transmission and drivetrain components is beneficial, prolonged standing can accelerate rubber and polymer ageing, promote corrosion in the chassis and under‑body, and lead to battery and fluid degradation if the car has not been regularly run or serviced. For a prospective buyer, the first visual checks should focus on the tyre condition; examine the tread depth and, more importantly, the sidewalls for any cracking, dry‑rot or hardening that can occur with age even on low‑mileage tyres. Verify that the 12‑volt battery holds a healthy charge and inspect the terminals for corrosion, as batteries left idle for years lose capacity and may leak acid. All fluid reservoirs—engine oil, coolant, brake fluid and the SMG transmission fluid—should be inspected for colour, level and any signs of contamination; time‑based fluid changes are recommended even if the mileage does not suggest it, particularly for brake fluid which can absorb moisture and affect braking performance. Finally, a thorough mechanical inspection should include the suspension bushings, ball joints and coil springs, which can become brittle or develop cracks after two decades regardless of mileage. Check the brake discs and pads for surface rust, glazing or uneven wear, and confirm that the calipers move freely without binding. Given the M5’s SMG gearbox, a test of the gear‑shift response and a check for any clunk or hesitation are advisable, as the hydraulic clutch and electronic controls can suffer from fluid breakdown or seal leakage over time. A review of the service book for regular oil changes, timing‑chain service and any major component replacements will further corroborate the car’s overall roadworthiness.
