2012 Mercedes-Benz SLK 2.5L Diesel · B20 MAG

A consistent pattern of uninterrupted passes characterises the roadworthiness history of this Mercedes-Benz SLK, culminating in a successful MOT test on the fifteenth of July 2026 at 45,416 miles. While the vehicle has never recorded an outright test failure across its eight documented examinations, the history is not entirely free of wear indicators. Recurring advisories regarding tyre edge wear appeared across multiple consecutive tests in 2023 and 2024, while the most recent 2026 inspection noted a light misting of oil on the offside front shock absorber. These points demonstrate that the mechanical hardware is experiencing standard operational degradation despite the absence of formal test refusals. Covering roughly 3,244 miles per year over its fourteen-year lifespan, this SLK presents an exceptionally low mileage accumulation rate. Such sparse usage means the vehicle has spent prolonged periods parked or operating exclusively on short journeys, which can accelerate localized component aging through under-use rather than high-mileage friction. There are no suspicious testing gaps in the DVSA log, indicating regular annual presentation for roadworthiness tests, but the low overall mileage profile necessitates a careful physical inspection of rubber components, exhaust integrity, and braking surfaces that may suffer from surface corrosion or lack of regular thermal cycling. During a physical viewing and test drive, specific attention must be directed toward the suspension and tyre tracking. Given the advisory history for edge wear on multiple tyres, check the inner and outer treads closely for uneven shoulder wear, which often points to geometry misalignment or worn steering joints. Listen carefully for any knocking, thumping, or excessive float over speed bumps or rough road surfaces to assess whether the offside front shock absorber, noted in 2026 for a light misting of oil, has suffered a complete internal seal failure requiring replacement. Inspect the front suspension wishbones, drop links, and anti-roll bar bushes for play or perished rubber. Further inspection should cover the underbody where the engine covers and undertrays are fitted, as technicians frequently note these shields during tests because they obscure internal components from routine view. It is advisable to remove these undertrays or inspect the engine bay from above to trace the source of any oil dampness associated with the front shock absorber or surrounding auxiliary systems. Finally, test the braking system thoroughly on a clear stretch of road to ensure the discs and pads, which may see less intensive use on a low-mileage car, are free from heavy pitting, corrosion, or binding calipers that could cause steering pull or pedal vibration.
