2007 Mercedes-Benz CLK 2.1L Diesel · Y17 SAU

The vehicle’s most recent MOT test on 2026-01-26—just six months ago—confirmed it passed with no defects recorded, though the preceding test on 2025-12-01 resulted in a failure for an unspecified reason despite identical mileage. This abrupt reversal suggests either a last-minute pre-test repair or a genuine oversight in the tester’s report, as no defects were logged. The pattern of two consecutive tests at 140,157 miles in September 2024—one pass, one fail—without explanatory notes further complicates interpretation, but the most recent clean pass indicates no immediate red flags. That said, the lack of advisories or minor faults in any test implies either meticulous maintenance or a vehicle that has not yet developed significant wear, though this cannot be confirmed without further inspection. The recorded mileage of 144,850 miles over nearly 19 years averages approximately 7,624 miles annually, which is typical for a vehicle of this age. The gap between the 2023 and 2024 tests—roughly 15,000 miles—suggests consistent use without prolonged periods of inactivity, which could mitigate some wear concerns. However, the identical mileage at the 2024 tests (140,157 miles) implies either a reset or an error, as mileage should increment. This inconsistency alone warrants scrutiny, as it may indicate tampering or an unreliable odometer. The most recent test’s clean pass at 144,850 miles does not provide clarity on whether critical components were serviced between tests, particularly given the vehicle’s age. Given the lack of specific defects in the MOT history, a buyer should prioritise an independent inspection of high-wear areas that are not routinely checked by MOT testers. The suspension—particularly the coil springs, bushes, and dampers—should be examined for uneven wear or corrosion, as these are common failure points in a vehicle of this age and mileage. Brake systems, including caliper binding, disc thickness, and pad material, must be assessed, as repeated braking performance issues could indicate underlying problems not captured in the MOT. Structural integrity, especially around the frame rails, sills, and wheel arches, should be inspected for rust penetration or weld repairs, as these are often overlooked until they compromise safety. The exhaust system and emissions components should also be checked, as catalytic converter failures or leaks are not always detected until they become severe. Finally, the electrical system, including battery health and wiring integrity, should be tested, as age-related degradation can lead to intermittent failures.
