2021 Ford Mustang Mach 1 5.0L Petrol · MU57 MAC

The 2021 Ford Mustang Mach 1 presents a clean and stable roadworthiness record. The most recent MOT on 17 June 2025, at 3,958 miles, passed with zero defects. This follows a clean pass on 20 June 2024 at 3,260 miles. A single failure occurred the day prior, on 19 June 2024 at 3,182 miles, but the official record shows no defects listed for that test, indicating a likely administrative or procedural failure that was immediately rectified. The trend is one of consistent, trouble-free maintenance with no recurring mechanical or structural advisories. The mileage profile is exceptionally low for a five-year-old vehicle. Between 19 June 2024 and 17 June 2025, the car covered just 698 miles. The gap between the 2024 and 2025 tests shows minimal use, averaging roughly 792 miles per year since manufacture. Such low annual mileage suggests extended periods of standing, which carries its own risks. Long immobility can lead to flat-spotted tyres, brake disc surface corrosion, and dried-out rubber seals. The sparse but consistent annual testing pattern indicates the owner maintained legal compliance despite limited use. A clean MOT record on a low-mileage performance car is encouraging but does not replace a physical inspection. The Mustang's high-performance brakes, low-profile tyres, and sophisticated suspension are sensitive to misuse and neglect. A buyer should closely inspect the inner rim edges for kerb damage and uneven tyre wear, common on powerful rear-wheel-drive cars. The underside must be checked for corrosion, particularly around subframes, suspension mounting points, and brake lines, as even low-mileage vehicles can suffer if stored in damp conditions. The drivetrain and cooling system warrant attention. A car driven infrequently and never reaching full operating temperature risks internal condensation and moisture accumulation in oil and coolant. Inspect the engine oil for a milky appearance and check the coolant level and condition. Test the brakes for binding or judder, as calipers can seize from disuse. The interior electronics and battery health should be verified, as deep discharge from long stand times is a known failure point. This vehicle's record is technically sound, but its usage pattern demands a thorough pre-purchase inspection focused on the hidden risks of minimal use.
