Our Verdict
A strong recommendation for buyers seeki
Buyers should prioritise a thorough review of the service history to ensure the 2993cc engine has been maintained according to BMW's specified intervals. Given the performance nature of the M4 Competition, check for any evidence of track use, such as excessive brake disc wear or tyre scrubbing, which may not be captured in MOT records.
Negotiate based on the remaining tread depth of the tyres and the condition of the brake components. As high-performance tyres are expensive and a common failure point for this model, replacing them shortly after purchase can be a significant unplanned cost.
Running costs for this vehicle will be high due to the 3.0L petrol engine and high-performance specifications. Expect significant expenditure on premium fuel and high insurance premiums associated with the M4's insurance group.
Maintenance costs will be higher than a standard 4 Series, particularly for specialised M-division parts. Annual costs will include the road tax for a high-emission petrol vehicle and the replacement of high-wear items like performance tyres and brake pads.
Inspect the offside side repeater light to confirm the previous failure was correctly rectified. Pay close attention to the hydraulic brake callipers and brake hoses, as these are identified as common failure points across the 1,352 vehicles analysed in the model aggregate data.
Carefully examine all four tyres for uneven wear or damage, as tyres are the most frequent MOT failure reason for this model. Ensure there are no leaks around the engine bay and check that all electronic systems are functioning correctly.
This 2021 Grey BMW M4 Competition has a recorded mileage of 28,447 miles as of its last MOT test in November 2025. The vehicle's history shows four tests with only one failure for a side repeater light, which was resolved on the same day. It aligns well with the model's aggregate data, presenting as a typical example of this Euro 6 AP petrol variant.
The M4 Competition has a strong reliability reputation based on aggregate data, boasting a 92.1% MOT pass rate across 1,352 analysed vehicles.
