2003 Mercedes-Benz SLK 2.3L Petrol · YY03 OBW

This Mercedes-Benz SLK from 2003 has demonstrated a stable roadworthiness trend over the past five years, with both MOT tests—conducted on 26 March 2026 and 8 September 2021—resulting in clean passes at 81,551 and 80,775 miles respectively. No defects were recorded in either instance, indicating that the vehicle has not experienced any recurring mechanical or structural issues requiring attention during these intervals. The most recent test, just over four months ago, confirms the car remains compliant with current UK roadworthiness standards, though a thorough in-person inspection remains essential to verify the condition of components not routinely assessed in an MOT. The recorded mileage of 81,551 miles over 23 years suggests an exceptionally low annual average of approximately 3,546 miles, well below typical usage patterns for a vehicle of this age. This could imply limited active use, extended periods of storage, or consistent off-road operation where mileage accumulation is slower. The gap between tests—nearly four years between the 2021 and 2026 MOTs—is within legal limits but raises questions about whether the vehicle was driven regularly during this period. Without additional service records, it is impossible to confirm whether critical maintenance, such as fluid changes or suspension inspections, was performed as recommended. Given the sparse MOT history, a buyer should prioritise an inspection of high-wear components that are not routinely tested. The absence of recorded defects does not preclude issues with suspension bushes, coil springs, or steering linkages, which may degrade silently over time. Brake components—particularly rear calipers and discs—should be checked for uneven wear or binding, as these are common failure points in older Mercedes-Benz models. Additionally, the underbody should be examined for corrosion, particularly around the sills, wheel arches, and exhaust system, as prolonged periods of inactivity can accelerate rust formation. Engine bay fluids should be inspected for leaks or discolouration, and the electrical system tested for reliability, as wiring and connectors can degrade over extended periods of non-use.
