1997 Mercedes-Benz 300 3.0L Diesel · G3 OOW

The vehicle’s most recent MOT test on 2025-04-22 confirms it remains roadworthy, with no defects or advisories recorded. This marks a stable pattern over the past three years, as all prior tests—including the 2023 and 2022 cycles—also passed without fail. The absence of recurring advisories suggests no persistent mechanical issues have been overlooked, though the 2023 test date appears duplicated (both a pass and a fail on the same day), which may indicate an administrative error rather than a technical concern. The lack of advisories on critical components like suspension bushes, coil springs, or binding calipers implies these areas have not been flagged for imminent failure, but wear remains a consideration given the vehicle’s age. The recorded mileage of 182,976 miles over approximately 29 years equates to roughly 6,310 miles annually, a rate consistent with typical usage for a vehicle of this vintage. There are no obvious gaps in maintenance intervals, though the MOT history is sparse before 2021, with no tests recorded between 2020 and 2021. This could reflect either a period of infrequent use or a lack of official testing records. The steady mileage accumulation suggests consumable components—such as brake discs, tyres, and wiper blades—have been subject to gradual wear, though no specific failures are documented in the MOT history. Given the vehicle’s age and mileage, a prospective buyer should prioritise an in-person inspection of high-wear areas not covered by the MOT. Focus on the suspension system, particularly the condition of rear bushes and coil springs, as these are prone to deterioration in older Mercedes-Benz models. Binding calipers or uneven brake pad wear should also be checked, as these can develop without immediate MOT failure. Structural integrity, especially around the chassis and wheel arches, warrants scrutiny for corrosion, particularly if the vehicle has spent time in wet or coastal environments. The absence of advisories does not preclude hidden issues, so thorough examination of the engine bay for leaks, the exhaust system for cracks, and the interior for excessive wear on critical controls is advisable.
