Mechanical Assessment

AI-generated interpretation of this vehicle’s MOT record — not an official statement and not a substitute for an independent inspection.

The vehicle currently maintains a stable roadworthiness status, evidenced by the most recent MOT test conducted on 25 March 2026 at 41,485 miles which passed with no recorded defects. This indicates that the car meets minimum regulatory standards. The maintenance trend appears improving, as the only noted wear item identified in the previous year has been addressed before the latest inspection. The mileage pattern is consistent with a five-year-old vehicle, averaging approximately 8,300 miles per annum. Between the March 2024 test at 14,950 miles and the March 2025 test at 28,812 miles, the car covered 13,862 miles, showing a slightly higher rate of use during that period. However, the subsequent interval of 12,673 miles leading to the 2026 test shows a return to typical usage levels. A buyer should focus their physical inspection on the braking system, as the March 2025 record flagged thin rear brake pads at 28,812 miles. While the latest test passed, a manual check should verify the remaining thickness of the pads and inspect for uneven wear or scoring on the discs. Given the relatively low mileage, the suspension components and rubber bushes should be in good condition, but checking for any dry rot or cracking is wise if the vehicle has sat for long periods between services.

Our Verdict

This is a strong used buy with a clean recent MOT record and sensible mileage for its age. The only caution is the noted rear brake wear in 2025, which is a routine consumable rather than a structural concern.

Ask to see the service history to confirm the rear brake pads flagged in March 2025 were replaced, and that routine servicing matches the mileage intervals. As a 2021 petrol A-Class with the 1.3-litre engine, it benefits from Mercedes-Benz's newer MBUX infotainment and Euro 6 AP compliance, so check the screen, connectivity, and that all software functions work as expected. Negotiate on the basis of the 41,485 miles recorded; it is average rather than low, so a fair price reflecting three years of normal use is appropriate rather than a premium for low mileage.

The 1332cc petrol engine in this A-Class typically returns mid-40s mpg in real-world mixed driving, keeping fuel costs reasonable for a premium hatchback. As a Euro 6 AP petrol registered in March 2021, it falls into a standard VED band with no expensive premium car tax applying due to its list price likely under the threshold. Insurance group will be mid-to-high for the class given the Mercedes badge, and maintenance at a main dealer is costly, so budget for independent specialist servicing where possible; estimated annual running cost is around £1,200-£1,500 including fuel, tax, insurance, and routine upkeep.

The MOT history shows only one advisory — rear brake pads wearing thin at the 2025 test — so verify on inspection that the pads and discs are now in good condition with even wear. Check the bodywork on this black example for stone chips and swirl marks, as dark paint shows imperfections more readily than lighter colours. Confirm the 41,485-mile odometer reading matches the MOT record and service book, and inspect tyres for tread and age given the annual mileage accumulation.

The 2021 Mercedes-Benz A 1332cc petrol (LS21ACU) shows a consistent MOT history with passes in 2024, 2025, and 2026 and no failures recorded. Mileage has risen from 14,950 in March 2024 to 41,485 by March 2026, averaging roughly 13,000 miles per year which is in line with typical UK use. The only advisory was rear brake pads wearing thin at the 2025 test, since resolved by the clean 2026 pass. No aggregate model reliability data was available, but the individual history for this car is reassuring.

No aggregate MOT reliability data was available for the Mercedes-Benz A model to draw broader conclusions from.
