2017 Mercedes-Benz B-Class 1.6L Petrol · LF17 ABK

This Mercedes-Benz B-Class has maintained an exemplary MOT record over the past two years, with the most recent test in May 2025 at 40,420 miles showing no defects whatsoever. The trend is stable and positive, with consecutive annual passes—April 2024, 2023, and 2022—all recording zero advisories or failures. Such a clean history suggests either meticulous maintenance by previous owners or, more likely, minimal use given the vehicle’s age. The absence of even minor advisories (e.g., tyre wear, wiper condition) is unusual for a car of this vintage and mileage, raising questions about whether routine servicing has been fully adhered to or if the vehicle has spent extended periods in storage. The mileage accumulation is exceptionally low for a nine-year-old vehicle, averaging just 4,491 miles per year—a figure more typical of a secondary or occasional driver’s car. The gap between the 2022 test (31,808 miles) and the 2025 test (40,420 miles) spans nearly three years with only 8,572 miles added, reinforcing the impression of light usage. This could indicate the car was rarely driven, possibly stored for long periods, which may have contributed to the pristine MOT results but also raises concerns about fluid degradation (e.g., brake fluid, coolant) or battery health if not properly maintained during inactivity. Given the complete absence of advisories or defects in the MOT history, a buyer should still conduct a thorough pre-purchase inspection focusing on components not routinely checked in an MOT. Priority areas include the suspension—specifically the condition of coil springs, anti-roll bars, and bushings—since low-mileage vehicles can still develop wear if subjected to potholes or rough roads. The brakes should be checked for binding calipers or uneven disc wear, even though the MOT has not flagged issues, as corrosion or fluid contamination can occur without active use. Structural integrity, particularly around wheel arches and underseal, should be examined for early signs of corrosion, especially if the car has been exposed to salt or moisture during storage. Finally, a fluid check—oil, brake fluid, and coolant—is critical, as stagnant fluids can degrade over time and lead to hidden mechanical problems. While the MOT record is flawless, the unusually low mileage and extended gaps between tests warrant caution. A buyer should verify whether the vehicle has been properly serviced and driven regularly, as the lack of advisories may mask deferred maintenance. If purchasing, insist on a full service history and consider a pre-purchase inspection by a Mercedes-Benz specialist to confirm no underlying issues have developed.
