2005 MG ZR 1.8L Petrol · MG05 ADN

The vehicle is currently roadworthy but the maintenance trend shows a shift toward addressing age-related component degradation. The most recent test in September 2025 at 83,687 miles identified specific advisories regarding corroded rear coil springs on both sides and a pitted offside rear brake disc. While the vehicle passed, these findings indicate that the suspension and braking hardware are beginning to succumb to age and corrosion, suggesting that the car is entering a phase where more frequent intervention is required despite the low mileage. The mileage profile is exceptionally low for a 21-year-old vehicle, averaging approximately 4,000 miles per year. There is a significant gap in usage between June 2019 and June 2022, where the car covered only 4,769 miles over three years, followed by a more active period in 2023 with 4,298 miles driven in one year. This low-frequency use often leads to the drying of rubber components, which is evidenced by the perishing and cracking of tyre sidewalls recorded during the 2019 inspection. A buyer must conduct a thorough inspection of the structural integrity, particularly the sills where covers were noted in 2025, as these often hide significant rust on MG models. The corroded rear coil springs should be checked for hairline fractures, as structural corrosion can lead to sudden failure. Given the history of a binding offside front brake in 2019 and the pitted rear disc in 2025, the buyer should verify that all calipers move freely and discs are not seized. Additionally, the age of the tyres is more critical than the tread depth; as the vehicle has sat for long periods, the rubber may rot regardless of the remaining life.
