2005 BMW M5 5.0L Petrol · M10 CYL

A recurring theme in this M5’s MOT record is the borderline condition of its tyre tread, brake discs and lighting – items that have repeatedly triggered advisories, major failures and a dangerous tyre defect. The 2022 test recorded a rear tyre below the legal 1.6 mm depth and an off‑side rear tyre with a cut reaching the ply, while the 2021 and 2019 tests flagged front brake discs as pitted and scored and both front position lamps as non‑functional. Most recently, the 2026 MOT passed overall but noted a non‑functional front registration plate inscription, a minor PRS issue that still requires correction before the next test. With 79,450 mi logged over 21 years the average annual accumulation is roughly 3,800 mi, well below the typical usage for a high‑performance sedan. Such low mileage can indicate periods of limited running, which may allow corrosion or rubber hardening to develop unnoticed, but it also means that wear items such as tyres, brake discs and suspension components have not been subjected to the high‑kilometre fatigue that would normally expose latent defects. The MOT history shows gaps in the publicly available data for 2020, 2023‑2025, so a prospective buyer should verify that the vehicle has retained a valid MOT each year and request any missing certificates to confirm continuous compliance. When inspecting the car, focus first on the tyre condition: look for uneven wear patterns, sidewall cuts or bulges, and verify that tread depth exceeds 1.6 mm on all four tyres. During a low‑speed test drive, listen for any thumping or vibration that could indicate a damaged tyre or a loose wheel nut – the 2021 failure cited a missing front wheel fixing, so all wheel bolts should be present and torqued to specification. Examine the brake discs for surface scoring, glazing or excessive rust; a pulsating pedal or squealing noise under moderate braking would confirm that the previously noted pitting has progressed. Check that both front headlamps illuminate within the correct aim envelope and that the position lamps flash correctly on each side, as mis‑aimed lamps and failed position lights have been a repeated issue. Finally, confirm that the SRS warning indicator remains off; a lingering fault could point to a sensor or airbag module problem that was flagged as a major defect in 2022. Given the pattern of safety‑critical components reaching the end of their service limits, a thorough pre‑purchase inspection by a specialist familiar with the E60 M5 platform is essential. Replace any tyre that is close to the legal limit, consider resurfacing or fitting new brake discs, rectify the headlamp aim and ensure the registration plate is legible. A diagnostic scan of the airbag control unit should be performed to clear any stored fault codes before the vehicle is driven regularly. Only after these items are addressed should the buyer assess the overall condition of the chassis, suspension bushes and drivetrain, which, while not flagged in the MOT record, will influence long‑term reliability on a high‑output model of this age.
