Our Verdict
Recommended, provided the recent engine
The primary point of negotiation and investigation should be the engine MIL malfunction recorded in November 2025. Request the diagnostic report and the invoice for the repair to confirm that the underlying cause was fixed rather than simply reset. Given the low annual mileage for a large diesel, check the service history for evidence of regular oil changes to prevent carbon buildup common in under-used diesel engines.
Ensure that all tyres have been replaced since the 2024 MOT, as the record noted cracking and perishing on the front and nearside rear. Verify that the offside front indicator is fully operational, as this was a cause for failure in 2024.
Running costs for this 2987cc diesel will be significant. While the Euro 6 AD status ensures compliance with most UK clean air zones, the vehicle's size and engine capacity place it in a higher tax bracket and insurance group.
Maintenance costs for the GLS are typically premium, reflecting its position in the Mercedes-Benz range. Expect higher-than-average costs for consumables such as tyres and brake pads, which are noted as common failure points across the wider GLS model population.
Carefully inspect the tyre sidewalls for any signs of cracking or perishing, referencing the failures recorded in November 2024. Check the dashboard for any active warning lights, specifically looking for the engine management light that caused the failure in late 2025.
While this specific vehicle has not recorded brake failures, the aggregate data for the GLS shows brake pads and service brake efficiency as top failure reasons. A physical inspection of the brake pad thickness and a test of the braking feel are advised.
This 2019 black Mercedes-Benz GLS diesel has recorded 40,893 miles as of November 2025, which is notably below the model average. Its MOT history shows a pattern of minor failures, including tyre perishing and a recent engine management light (MIL) malfunction. Despite these, the vehicle has passed its most recent tests and remains Euro 6 AD compliant.
The GLS maintains a strong aggregate MOT pass rate of 90.5%, with most failures attributed to routine wear-and-tear items like tyres and brakes.
