What to check on a 2016 Mercedes-Benz GLC before buying
The three areas where failed first tests most often had a fault, 2023–2025.
- Suspension. Worth looking behind the front wheels with a torch at the coil springs, and listening for knocks over bumps on the test drive.
- Tyres. Worth checking the tread depth across the whole width of each tyre, and the sidewalls for cuts, cracks and bulges.
- Engine and emissions. Worth checking that the engine warning light goes out after starting, looking for oil leaks under the car, and noticing any smoke from the exhaust.
