2004 MG ZR 1.8L Petrol · AF04 BKF

The most recent DVSA examination on 22 December 2025 resulted in a Pass, though three advisories were issued relating to front brake binding on the nearside and both front tyres being worn close to the legal limit and worn on the edge. Comparing this result to the prior tests, the maintenance trend appears broadly stable rather than deteriorating, but there is a clear pattern of recurring front brake and front tyre concerns. The vehicle previously failed on 4 January 2023 due to excessively corroded rear suspension mounting areas on both sills, which is a serious structural finding that was apparently rectified given subsequent passes, alongside ongoing advisories for oil leaks, track rod end play, and brake pad wear. The repeat advisories for front brake binding across multiple consecutive tests suggest an underlying caliper or slider issue that has not yet been fully addressed, while the front tyre wear pattern on both sides points to a possible tracking or suspension geometry concern that warrants further investigation. With a recorded mileage of 123,720 miles over approximately 22 years, this MG ZR has averaged around 5,600 miles annually, which is notably low for a vehicle of this vintage and suggests significant periods of standing or only occasional use. Low annual mileage of this nature reduces wear on major drivetrain components but often accelerates degradation of items that suffer from inactivity, such as brake discs corroding and calipers seizing, rubber components perishing, and fluids degrading due to age rather than use. Any prospective buyer should therefore be alert to condition-based deterioration rather than assuming low miles equate to a sound mechanical state, and should verify whether the recorded figures are consistent with the wear actually present on the vehicle. Given the history of front brake binding advisories appearing on nearly every recent test, particular attention should be paid to the front calipers, guide pins, and brake pads during a physical inspection. A test drive should include several firm stops from moderate speed to check for pulling to one side, grinding noises, or a pulsating brake pedal, as well as a check for the front wheels running hot shortly after driving. The advisories for front tyres worn close to the legal limit and on the edge, repeated on both sides over consecutive tests, strongly suggest a tracking or suspension geometry issue such as worn bushes, a bent component, or simply the need for a four-wheel alignment and replacement tyres, and this should be factored into any purchase negotiations. The advisory concerning an oil leak, present on every test since 2021, indicates a persistent seep that has so far been deemed not excessive, but it should be monitored closely as the leak source could be from the rocker cover gasket, sump, or cam cover, and any worsening should prompt immediate investigation to prevent engine damage. The 2024 advisory regarding a nearside front shock absorber with reduced damping effect suggests progressive wear of the front suspension, which would manifest on a test drive as excessive bouncing over bumps, poor cornering stability, or a clonking noise from the front end over uneven surfaces. Beyond the recorded defects, this 22-year-old vehicle warrants thorough age-related inspection regardless of its modest mileage. The brake discs are likely to show corrosion pitting and lip formation due to standing periods, and the calipers may have seized pistons or stiff slider pins that bind under light pedal pressure. Tyres older than five or six years should be examined closely for sidewall cracking and perishing even if tread depth appears adequate, and the spare wheel should be checked for age-related deterioration. The 12 volt battery should be load tested, as prolonged standing is highly detrimental to battery longevity and a failing battery is a common cause of non-starts. All fluid services should be verified by service book evidence, including the coolant, brake fluid, and gearbox oil, as these degrade with calendar age and may not have been refreshed regularly given the low annual mileage. The exhaust system, including the catalytic converter and rear silencer, should be inspected for corrosion and security, and the underside should be examined on a ramp for any fresh corrosion, particularly around the repaired rear sill areas where the previous structural failure occurred. Finally, given the age of the vehicle, checking for any signs of timing belt or chain service history, where applicable, along with verifying the operation of all auxiliary systems including the rear fog lamp and seatbelt retractors that previously failed, would be prudent steps before committing to purchase.
