2017 Mercedes-Benz B-Class 2.1L Diesel · J3 RFG

The 2017 Mercedes-Benz B-Class presents a clean roadworthiness status with a stable maintenance trend. The most recent test on 22 July 2025 at 28,495 miles returned a pass with no defects recorded, continuing an unbroken sequence of passes since the earliest entry in this history. No advisories or mechanical faults appear at any stage, indicating the vehicle has not required corrective work across the recorded period. Annual mileage sits well below typical expectation for a nine-year-old car. The record shows 13,032 miles at the April 2021 test, rising to 17,431 by April 2022, 20,669 by July 2023, 24,678 by June 2024, and 28,495 by July 2025. That equates to roughly 3,166 miles per year, with only a minor gap between the 2022 and 2023 tests where the interval extended to just over fourteen months. The clean sheet across all entries suggests either careful low-use ownership or a vehicle kept largely idle for extended periods. Given the absence of flagged defects, the buyer should still verify in person the condition of consumable items that a pass does not exempt from wear. Low mileage combined with standing time can allow brake discs to develop surface corrosion and suspension bushes to stiffen without showing in the MOT. A visual check of tyre sidewalls, underbody structural integrity, and exhaust emissions hardware remains sensible. No recurring problems or serious structural risks emerge from the DVSA data. The previous keeper appears to have maintained basic upkeep to a standard that avoided test failures. A pre-purchase inspection should focus on confirming the low-use pattern has not concealed intermittent faults outside the test window.
