2004 MG ZT-T 2.0L Diesel · SH54 VGE

The 2004 MG ZT-T passed its most recent MOT on 5 September 2025 at 245,392 miles, but the maintenance trend is not reassuring. The tester flagged worn inner tyres on the offside front and nearside rear, slight play in the nearside front anti-roll bar ball joint, and corrosion at both rear jacking points. These advisories point to a car that is holding together but showing its age through deteriorating rubber components and localised structural corrosion rather than catastrophic mechanical failure. The pattern across the last five years is one of gradual decline rather than active neglect, yet nothing suggests a recent round of preventative work. Mileage accumulation is broadly consistent with a typical 22-year-old vehicle, averaging roughly 11,154 miles per year. The record shows a steady climb from 209,139 miles in September 2021 to 245,392 miles in September 2025, with no large gaps or sudden drops that would indicate long-term storage or a rolled-back odometer. Annual tests have been completed each September without interruption, which at least confirms the car has remained in regular use and has not been left standing for extended periods that could cause seizure or fluid degradation. A buyer should focus the physical inspection on the areas the MOT has repeatedly highlighted. Underbody corrosion has appeared in three of the last five tests, with the rear jacking points specifically called out in 2025. That is a useful indicator of how the sills, subframe mounts, and floor pans may be deteriorating, so a thorough check with a torch and probe is essential before committing. The exhaust has emitted visible smoke or vapour in four consecutive tests, which on a 2.5-litre V6 of this age could point to worn valve stem seals, piston ring wear, or a failing catalytic converter, and a compression test or borescope inspection would help clarify the engine's internal condition. Suspension and braking components also warrant close attention. The nearside front anti-roll bar ball joint has shown slight play in two separate tests, suggesting the bushes and links on both sides are likely due for replacement. Front brake fluctuation was noted in 2022, and while it did not fail the test, uneven disc thickness or a sticking caliper could still be present. Tyre wear has been a recurring theme, with inner edge wear appearing repeatedly, which typically indicates worn suspension geometry, tired dampers, or misaligned tracking. Any test drive should assess steering precision, body roll, and braking stability, and a fresh four-wheel alignment check is strongly advised before purchase.
