1990 Mercedes 300 3.0L Petrol · H828 NFX

The vehicle presents a stable roadworthiness profile, showing a consistent maintenance trend despite minor mechanical setbacks. The most recent test in October 2025 at 147,232 miles passed with an advisory for a front oil leak that the tester deemed not excessive for road use. This follows a successful repair in October 2024 where the car failed by just one mile due to a leaking rear fuel system component, suggesting the current ownership is responsive to safety-critical MOT failures. At 36 years of age, the recorded mileage of 147,232 miles represents a low annual average of approximately 4,100 miles per year. The data shows consistent usage patterns with intervals of roughly 1,000 to 3,000 miles between annual tests from 2022 through 2025. This low mileage suggests the vehicle has not been subjected to heavy heavy-duty wear, though low-mileage vehicles often suffer from degradation of rubber components, seals, and fluid chemistry due to age and potential long periods of inactivity. A physical inspection should focus specifically on the front oil leak noted in the 2025 record to determine if the source is a simple seal or a more significant gasket failure. Given the previous fuel system failure, the buyer must also verify the integrity of the fuel lines and connections for corrosion or embrittleness. While the MOT record shows no structural advisories, a thorough check for rust in the sills, wheel arches, and chassis rails is essential, as these are common failure points for Mercedes models of this era regardless of mileage.
