2011 MG 6 1.8L Petrol · YX11 BBJ

The vehicle's roadworthiness is currently questionable due to a worsening trend in structural and corrosion-related issues. While the November 2025 test at 58,420 miles resulted in a pass, the immediate preceding failure in September 2025 at 58,408 miles revealed serious structural defects. The tester flagged excessive corrosion on the nearside and offside rear inner vehicle structures, specifically within 30cm of a body mounting inner sill, which significantly compromised the chassis strength. Although these structural issues were addressed to secure the pass, the history shows a persistent pattern of corrosion affecting brake pipes and suspension mounting areas. The vehicle has covered 58,420 miles over approximately 15 years, averaging roughly 3,895 miles per year. This low annual mileage suggests the car has seen light use, yet the MOT records indicate long periods of inactivity or poor storage. The significant jump in mileage between June 2017 at 45,656 miles and July 2018 at 53,601 miles shows a period of higher usage, but the subsequent years show very slow accumulation. This low usage pattern often correlates with the rubber degradation and perishing tyres noted in the 2022, 2024, and 2025 tests. A prospective buyer must conduct a thorough underside inspection, specifically focusing on the rear inner sills and suspension mounting points. The September 2023 failure at 56,868 miles highlighted excessive corrosion on the nearside rear spring hanger and sill area, and the September 2025 failure confirmed deep-seated structural corrosion. Because the record shows brake pipes have been consistently corroded or covered in grease since at least 2018, the integrity of the entire hydraulic braking system requires close scrutiny. The recurring advisories regarding perishing and cracking tyres across multiple years suggest that while the car is driven infrequently, the rubber components are aging poorly. The November 2025 test flagged cracking on the nearside front, offside front, and offside rear tyres, alongside a binding nearside front service brake. Beyond the structural concerns, the buyer should verify the condition of the exhaust system and ensure all recent repairs to the brake pipes and chassis have been carried out to a high standard to prevent rapid recurrence of these faults.
