2007 Mercedes-Benz B-Class 1.5L Petrol · KB07 AJB

The 2026-05-15 MOT pass marks the latest compliance checkpoint for this 2007 Mercedes-Benz C-Class, representing a stable return to clear roadworthiness after the significant failure encountered in July 2018. The vehicle’s recorded history shows a generally clean trajectory following that incident, with uninterrupted passing results from September 2019 through May 2026, each confirmed free of defects. While the 2018-07-26 failure introduced critical safety concerns that required remediation, the subsequent four years demonstrate consistent maintenance adherence until the current test cycle, suggesting that any underlying issues have been addressed and the car has regained its compliance status. The overall pattern is therefore one of intermittent reliability punctuated by a single major breakdown, rather than progressive deterioration across the engine or chassis systems. The odometer reading of 139,150 miles on approximately 19 years yields an average annual mileage of roughly 7,324 miles, which falls within the expected range for a vehicle of this age and class. This rate of accumulation is typical for moderate daily use and does not immediately suggest abnormal wear patterns on the drivetrain or suspension components. The gap between the 2018-07-26 failure and the next recorded test in 2019-09-06 spans nearly two years, indicating a period of undetected issues that were eventually surfaced, followed by a series of clean assessments that support the notion of sustained reliability thereafter. There are no indications of sudden mileage spikes or prolonged standstill periods that would accelerate component consumption; instead, the usage profile appears steady with minor fluctuations consistent with normal driving cycles. The most pressing mechanical considerations stem from the 2018-07-26 failure report, which identified severe brake pad wear on both the nearside and offside rears—each measured below the 1.5 mm threshold—and also noted the absence of the central front centre mirror along with non-functional reversing lamps and an improperly aimed front headlamp beam pattern. On a test drive, the buyer should pay close attention to how the vehicle responds over bumps and potholes, as corroded rear coil springs typically manifest as increased suspension travel, a hollowness in the ride quality, or difficulty maintaining straight-line stability when the springs are compromised. The brake pad measurements require particular scrutiny: the remaining material on both axle ends is critically low, meaning the pads are approaching or have potentially reached end-of-life, and any residual material could lead to inadequate stopping power or uneven pad contact. Additionally, the earlier missing mirror and faulty lighting indicators are cosmetic but signal that related electrical and chassis assemblies have experienced neglect, warranting a visual inspection of the entire rear light assembly and interior instrument cluster functionality prior to purchase.
