2021 BMW M4 Competition Auto 3.0L Petrol · HX71 XPR

The 2021 BMW M4 Competition Auto presents a clean MOT history, with both the November 2025 and October 2024 tests passing without any defects recorded. This indicates a stable roadworthiness trend, suggesting the vehicle has been well maintained in critical areas over the past year. The absence of advisories or failures in the most recent test at 28,108 miles—just six months ago—implies no immediate structural, mechanical, or safety concerns were identified by the tester. Such a record is uncommon for a high-performance vehicle of this age, particularly given the rigorous demands placed on its braking, suspension, and exhaust systems. The mileage pattern reveals a notably conservative usage profile, with only 5,223 miles covered between the two MOTs—a rate of roughly 5,622 miles per year over its five-year lifespan. This low annual mileage could reflect either careful ownership or extended periods of disuse, though it does not correlate with typical wear patterns for a performance car. The gap between tests is standard (just over a year), but the absence of any mileage spikes or advisories suggests the vehicle has either been stored with minimal use or maintained meticulously by owners who prioritise regular checks. Without additional service records, it’s impossible to confirm whether this low mileage has been achieved through diligent upkeep or simply limited driving. For a prospective buyer, the key focus should be on components not routinely covered by MOT tests but critical to long-term reliability. Given the car’s performance pedigree, inspect the rear suspension coil springs and bushes for wear or sagging, as these are prone to fatigue even at low mileages. Check for binding in the rear brake calipers—a common issue in high-performance BMWs—and verify the condition of the brake discs for uneven wear or heat cracks. The exhaust system, particularly the downpipes and catalytic converter, should be examined for leaks or corrosion, as these can degrade rapidly if the car has been left unused for extended periods. Finally, assess the condition of the tyres for age-related cracking, even if tread depths are legal, and verify the battery health, as low-mileage vehicles often suffer from reduced electrical cycling.
