Our Verdict
This 2015 Mercedes-Benz GLA diesel is a solid used buy with a largely clean MOT record and sensible mileage for its age. The only notable concern is a single 2024 failure for rear tyre wear, which was promptly corrected the same day.
When viewing this GLA, confirm that the rear tyres replaced after the July 2024 failure are still in good condition and check the overall tyre age, as the 2023 front tyres were noted as worn close to the limit and may now need replacing. Request the full service history to verify that the 2.1-litre diesel engine has had timely oil and filter changes, given its current 68,799-mile mileage. Use the clean recent MOT record as leverage, but note the 2024 tyre failure means the seller should have proof of the corrective work carried out.
As a 2143cc diesel, this GLA should return reasonable fuel economy, though exact figures are not provided in the data; diesel tax and insurance for a 2015 Mercedes-Benz SUV are typically moderate rather than cheap. Maintenance on Mercedes diesel models can be pricier than mainstream brands, so budget for servicing and any tyre renewals flagged in the MOT history. Estimated annual running costs including fuel, tax, insurance and typical maintenance are around £1,200-£1,500.
The MOT history shows a failed test on 11 July 2024 at 61,351 miles for Offside Rear Tyre worn on edge and Nearside Rear Tyre below 1.6mm tread, so physically check the current rear tyres for even wear and legal depth. The July 2023 pass noted both front tyres worn close to the legal limit at 55,379 miles, meaning front tyres may have been replaced since but should be inspected for condition and age. Beyond tyres, look for general diesel servicing evidence and any signs of neglect, as no other defects were recorded across the remaining MOTs.
The vehicle (KM15ACO) is a blue 2.1-litre diesel GLA first registered in March 2015 and has covered 68,799 miles as of its latest MOT in July 2025. MOT history shows four passes and one failure, with the failure limited to rear tyre tread issues that were resolved immediately on re-test. Average annual mileage works out at roughly 6,400 miles, which is modest for a ten-year-old car and suggests gentle use.
No aggregate MOT reliability data is available for the Mercedes-Benz GLA, so this assessment relies solely on the individual vehicle's history.
