Buying Tips for the 2020–2021 Mercedes-Benz GLC (X253)
- ✓Test drive the car on full steering lock at low speeds (like parking); early RHD models suffer from harsh tyre 'crabbing' or skipping, which cannot be fully cured.
- ✓Inspect the interior for trim rattles, particularly from the center console, floating infotainment screen, and door panels over rough roads.
- ✓On diesel models (OM651), listen for a brief rattle on cold start, which can indicate a stretching timing chain.
- ✓Verify the operation of the 9G-Tronic gearbox; downshifts should be smooth, and any hesitation may require a software update.
- ✓Check the Air Body Control suspension (if fitted) to ensure it raises the car evenly and doesn't display any dash warnings.
