2021 Mercedes-Benz A 1.3L Petrol · DY11 AAN

The 1,332cc petrol A-Class typically returns around 45-50 mpg on a motorway run and 35-42 mpg in mixed use, depending on driving style. Insurance for a 2021 A-Class in this trim tends to fall in groups 20-28, so quotes should be obtainable from mainstream insurers, though premiums will reflect the Mercedes-Benz badge.

Road tax is likely to be in the £150-£190 per year band given the engine size and Euro 6 AP emissions classification, though this should be confirmed via the DVLA VED calculator using the specific registration. Mercedes-Benz servicing tends to be pricier than mainstream brands, with annual maintenance commonly £300-£500 depending on whether an independent specialist or main dealer is used.

Given the MOT history, all four tyres should be examined closely — check the DOT date code on the sidewall, as tyres older than five years may perish regardless of tread depth. Uneven wear across an axle can point to alignment or suspension issues, so look for feathering on the inner or outer edges. The 2025 failure also flagged the windscreen wiper, so test both front wipers across their full sweep and ensure they clear the screen cleanly without smearing.

Beyond the MOT-flagged items, the M282 1.3-litre petrol engine shared with Renault should be inspected for any signs of oil consumption — ask to see the dipstick and check for mayonnaise on the oil cap, which can indicate head gasket concerns. Listen for timing chain rattle on a cold start, and ensure the auto stop-start function operates smoothly as this engine's start-stop system can occasionally flag faults.

The 2021 model year means this car should still be within Mercedes-Benz's extended warranty period if serviced on schedule, so request confirmation of the service history and any remaining warranty cover. Inspect the bodywork for parking scuffs typical of a city-driven premium hatchback, and check the MBUX infotainment screen for any pixel failures or unresponsive areas.
