2016 Mercedes-Benz GLC 2.1L Diesel · M800 AEC

The 2.1‑litre diesel in the GLC typically achieves around 45‑50 mpg combined, translating to roughly £800‑£900 per year on fuel assuming average UK mileage. Road tax for a diesel SUV of this size falls into the £210‑£250 band, and insurance groups for a 2016 GLC sit in the 30‑35 range, costing about £650‑£800 annually depending on driver profile.

Maintenance on a Mercedes‑Benz SUV is modest compared with performance models, but brake disc and CV boot replacements can add £400‑£600 every few years. Factoring in routine servicing, the estimated total annual running cost sits between £1,300 and £1,500.

Pay close attention to the rear drive‑shaft CV boots, which the 2025 MOT flagged as severely deteriorated on both sides. Check for any fluid leaks or unusual noises from the rear axle, as replacement can be costly. Also inspect the tyre condition – the MOT notes uneven wear on both rear tyres and a front tyre close to the legal limit – and verify that the tyres are of the correct specification for the GLC.

Examine the brake discs and pads for surface corrosion and wear, especially since multiple MOTs highlighted worn discs. While the advisories indicate the wear is not yet excessive, replacement may be imminent. Finally, ensure the front undertray is securely fastened, as the 2024 MOT noted it was not fully secure, which could lead to rust or aerodynamic noise if left unattended.
