2002 Mercedes-Benz C 2.7L Diesel · GU02 OGA

The Mercedes-Benz C-Class in question presents a concerning maintenance record, with the most recent MOT—conducted on 11 November 2022 at 151,471 miles—resulting in a fail despite no defects being recorded. This outcome is unusual, as a failed MOT typically requires at least one advisory or dangerous defect to be noted. The preceding test, just one year earlier on 12 November 2021 at 149,471 miles, also failed without defects, suggesting either a clerical error in documentation or an oversight by the tester. The absence of any advisories or failures in the intervening period implies either a vehicle in unusually good condition or a pattern of MOT stations unable to identify critical issues. Given the lack of recorded faults, the trend cannot be classified as worsening or improving—only that the car has not been subject to meaningful scrutiny in over three years, a significant red flag for a vehicle of this age and mileage. The mileage accumulation of roughly 6,311 miles per year aligns with typical usage for a 24-year-old vehicle, though the sparse MOT history raises questions about its actual condition. The two tests in November 2021 and 2022 show minimal mileage progression (just 2,000 miles over 12 months), which could indicate prolonged periods of inactivity or potential odometer manipulation. More troubling is the complete absence of MOT records between 2021 and 2022—a gap of over 12 months where the vehicle should have been tested annually. Under UK law, a car over three years old must undergo an MOT every 12 months, meaning this vehicle has been illegally untested for nearly four years as of July 2026. Such a prolonged absence from official inspection strongly suggests either neglect or deliberate avoidance of scrutiny, neither of which bodes well for its structural or mechanical integrity. For a prospective buyer, the primary concern lies in the lack of documented maintenance or MOT history —a critical omission for a vehicle of this age. Given the absence of recorded faults, the car may still harbour hidden issues, particularly in high-wear areas such as suspension bushes, coil springs, brake calipers, and hydraulic systems , all of which degrade over time without regular inspection. Structural corrosion, especially in the chassis, sills, and exhaust system, should be scrutinised thoroughly, as rust in these areas can compromise safety and longevity. The brakes, while not flagged in the sparse records, warrant immediate attention—binding calipers or uneven disc wear are common in neglected vehicles. Finally, the exhaust emissions system should be checked, as older Mercedes-Benz models are prone to catalytic converter failure or EGR-related issues, which could explain why no defects were recorded despite potential underlying problems. Without a comprehensive service history or recent diagnostics, this vehicle represents a high-risk purchase.
