2013 Mercedes-Benz GL 3.0L Diesel · G7 YDC

Tyre wear has been the most recurrent mechanical theme in the MOT history, highlighted by a dangerous rear‑tyre failure in September 2020 and repeated advisories on front‑tyre tread limits in 2019, 2021 and 2020. Since the 2020‑09‑28 advisory, the anti‑roll bar corrosion has been noted but not deemed structurally compromising, and rear‑brake pad wear has been flagged but never progressed to a failure. The three most recent tests (2023, 2024 and 2025) recorded no defects, indicating that the vehicle has been running without further MOT‑visible issues for the past three years. At 133,543 mi the vehicle averages just over 10 000 mi per annum, a mileage rate that sits squarely within normal usage for a 2013 model. MOTs have been logged annually apart from the missing 2022 entry, suggesting the car has not spent extended periods off the road. This moderate annual accumulation means consumables such as tyres, brakes and suspension components are likely to be in the mid‑life stage rather than approaching the end of their design life, but the earlier tyre‑related advisories imply that tread depth may now be approaching the legal minimum. A prospective buyer should give the tyre set a thorough visual and tactile inspection. Measure tread depth on all four wheels, looking especially for sidewall cuts on the rear tyres that previously caused a failure, and verify that the front tyres are not merely “worn close to the legal limit”. While driving, listen for low‑frequency thumps over bumps that could indicate deteriorating suspension bushes or a compromised anti‑roll bar, and feel for any pulling to one side that might betray uneven tyre wear or steering geometry issues. Test the rear brakes for pedal feel; a soft or spongy pedal could signal that the pads, already noted as thin, are nearing the end of their serviceable thickness. Finally, arrange a qualified pre‑purchase inspection focused on the rear anti‑roll bar corrosion, rear‑brake pad condition and the overall integrity of the suspension mounting points. Replacement of the rear tyre set is likely to be required in the near term, and the front tyres may also need attention if tread depth is marginal. Confirm that any child‑seat fittings do not obstruct adult belt inspection, as noted in 2018, and ensure that all safety‑critical components pass a hands‑on check before finalising the purchase.
