2018 Mercedes-Benz GLA 1.6L Petrol · AP18 AAU

The 2018 Mercedes-Benz GLA received its most recent MOT test on 21st November 2025, which resulted in a passing grade with several advisories rather than any failures. The pattern of advisories over the past three MOTs—particularly the consistent near and offside rear tyre cracking or perishing and the rear brake disc wear—suggests a stable maintenance trend with recurring but manageable issues rather than a deterioration in overall roadworthiness. The lack of failures or critical defects in the earlier MOTs from 2022 and 2021 indicates that while the vehicle has encountered some wear-related advisories, it remains in a functional state that meets the minimum legal standards. The presence of minor lighting discolouration and obstructed vision advisories from 2023 and 2024 are non-critical and likely due to minor cosmetic wear or installation practices rather than mechanical failure. The vehicle’s recorded mileage of 39,581 miles at the time of this assessment is unusually low for an eight-year-old car, averaging approximately 4,948 miles annually. This figure is significantly below the typical usage rate for a GLA, which often accumulates around 10,000 to 15,000 miles per year in active service. Such low mileage can stem from infrequent use, long periods of stationary storage, or a more leisurely driving profile, but it also raises concerns about potential standing-related wear. For example, prolonged idling or stationary periods can lead to brake disc corrosion, caliper binding, and fluid degradation in the cooling and hydraulic systems. Additionally, the tyre advisories—particularly the cracking or perishing—may be exacerbated by reduced rotation or uneven wear patterns, which can occur when a vehicle is driven infrequently or parked in specific orientations. Given the recurring tyre cracking advisories and the rear brake disc wear noted in the MOT history, the prospective buyer should conduct a thorough inspection of the tyres for signs of uneven wear, dry rot, or internal damage. On a test drive, listen for any unusual noises from the rear suspension or brakes, such as clunking from worn suspension bushes or coil springs, or a grinding sensation that could indicate brake disc or pad wear. The rear brake discs should be examined for signs of corrosion, pitting, or warping, which may require replacement if they are significantly worn or damaged. Additionally, check for any fluid leaks under the vehicle, particularly around the brake master cylinder, wheel cylinders, and exhaust system, as standing fluid can corrode internal components over time. The brake system should be tested by applying the brakes firmly while driving at low speeds to ensure consistent stopping power and no binding or excessive vibration. For the buyer’s practical assessment, focus on the vehicle’s physical condition and age-related wear, given the low mileage profile. Inspect the tyres for sidewall cracking or perishing, which can occur even with low mileage if the rubber has been exposed to prolonged sunlight or poor storage conditions. Verify the condition of the 12-volt battery, as prolonged disuse can lead to sulphation or reduced capacity, which may require a recharge or replacement. Check the brake discs for corrosion or binding, particularly if the vehicle has been stationary for extended periods, as this can cause the discs to stick to the calipers. Examine the cooling system for signs of fluid degradation, such as sludge or sediment, which may warrant a flush if the vehicle has been unused for a significant duration. Lastly, review the service history for any time-based maintenance, such as fluid replacements for the engine oil, brake fluid, and coolant, as these should be updated every 2–3 years regardless of mileage to maintain optimal performance and prevent premature failure.
