2005 MG ZT 1.8L Petrol · AS05 RTS

A decade of missing MOT data is the primary mechanical concern for this vehicle, following a period of recurring brake and corrosion advisories. The last recorded test on 7 September 2016 resulted in a pass but flagged corrosion on both rear upper suspension arms and worn, pitted rear brake discs. This deterioration of the rear braking system was a consistent theme across three consecutive tests between 2014 and 2016, indicating a long-term issue with the condition of the rear discs. With 85,065 miles recorded over 21 years, the vehicle has averaged approximately 4,051 miles per year, which is low for its age. However, the total absence of testing records from 2016 to 2026 suggests a significant period of dormancy. Such prolonged inactivity typically increases the risk of seized calipers, perished rubber seals, and accelerated corrosion of exposed metal components, potentially exacerbating the suspension issues noted in the final recorded test. Inspection should focus heavily on the rear axle and braking assembly. Given the repeated advisories for pitted and scored rear discs and the low reserve travel on the parking brake lever, a physical check for binding calipers or seized sliders is essential. During a test drive, feel for any judder through the brake pedal or an uneven pull under braking. The corrosion previously noted on the rear upper suspension arms requires a close visual inspection to ensure structural integrity has not been compromised during the vehicle's long period of inactivity. The 2012 record included a user-entered note regarding an oil leak, which should be verified by inspecting the engine bay and the underside of the chassis for residue. Listen for any abnormal knocks or clunks from the rear suspension when traversing uneven surfaces, as this could indicate that the previously corroded suspension arms or associated bushes have deteriorated further. Finally, verify the headlamp aim, as this was a specific point of failure in the vehicle's earlier history.
