1998 Mercedes-Benz C 4.3L Petrol · S121 AMG

The 1998 Mercedes-Benz C remains roadworthy with a stable maintenance trend. The most recent test on 10 December 2025 at 89,723 miles passed with no defects recorded, continuing an unbroken run of clean results across the available history. Mileage sits at 89,723 against a 28-year lifespan, averaging roughly 3,200 miles per year. The record shows sparse but consistent testing: 83,869 miles on 23 October 2020, then 86,104 on 17 June 2022 after a 20-month gap, and three annual passes through December 2025 reaching 89,723. Low annual use and the 2020 to 2022 lapse suggest the car spent long periods stationary, which raises the risk of perished rubber components and fluid degradation not captured by a pass result. No advisories or failures appear in the data, so the MOT gives no direct warning on suspension bushes, brake discs, or structural corrosion. A buyer should still commission a physical inspection beneath the sills and subframes for hidden rust, check for cracked coil springs from prolonged standing, and verify the brake calipers are not seizing after low-mileage dormancy. Given the clean record and minimal wear profile, previous owners likely kept basic statutory testing current without obvious neglect. The absence of flagged defects means mechanical risk rests on what the tester could not see rather than documented faults.
