2003 Mercedes-Benz ML 2.7L Diesel · SM53 AVL

This Mercedes-Benz ML from 2003 has demonstrated a stable but inconsistent MOT history, with the most recent test on 2025-11-01 resulting in a pass—despite an identical date entry showing a failure, which suggests a possible administrative duplication rather than a genuine retest. The previous clean pass in 2024-10-04 and the lack of recorded defects in any of the five tests spanning 2023 to 2025 imply that no major mechanical or structural issues were detected by the tester. However, the repeated failure on the same date in 2023—without explanation—raises minor concern over potential oversight or a non-critical fault that was rectified before the next test. Overall, the vehicle has not shown a worsening trend, but the absence of advisories or detailed defect codes means critical components like suspension bushes, coil springs, or binding calipers were not explicitly cleared. The mileage progression of 139,142 miles over 23 years reflects an average of approximately 6,050 miles annually, which is typical for a vehicle of this age and class. There are no significant gaps or abrupt spikes in the record, though the sparse data between tests—particularly the lack of intermediate mileage readings—makes it impossible to confirm whether maintenance was performed between MOT cycles. The most recent test was conducted just seven months ago, which is within the acceptable window for a used-car purchase, though the absence of advisories in the latest pass means no pre-existing issues were flagged for buyer awareness. Given the clean MOT history, a buyer should prioritise an independent inspection of high-wear components that often fail without clear MOT indicators. Focus on the suspension—particularly the rear bushes and coil springs—given the vehicle’s age, as these tend to degrade gradually without immediate failure. Check for binding rear brakes, which are common in older Mercedes models and may not always trigger an MOT failure until they become severe. Structural integrity should also be assessed, especially around the wheel arches and sills, where corrosion can compromise the chassis over time. While the MOT record suggests no major faults, these areas are prone to silent deterioration that only a thorough mechanical examination can reveal.
