1999 MERCEDES CLK3.2L PETROL

The vehicle currently holds an unroadworthy status following a failure in its most recent inspection. While the car maintained a clean record for several years, the maintenance trend is now worsening. The latest emissions test at 87,489 miles recorded a failure due to carbon monoxide levels exceeding legal limits. This mirrors a previous failure in July 2023 at 86,840 miles, indicating a persistent issue with the engine combustion process that has not been successfully rectified. The mileage profile is exceptionally low for a 27-year-old vehicle, averaging approximately 3,240 miles per annum. The data shows significant periods of inactivity; for instance, the car covered only 40 miles between the July 2023 and August 2024 tests. Between August 2024 and May 2026, the vehicle covered an additional 641 miles. Such low usage frequency often leads to the degradation of rubber components, dried seals, and fuel contamination from long sitting, which may explain the emissions-related failures. A buyer must prioritise a diagnostic check of the fuel and exhaust systems to address the recurring carbon monoxide failures. High emission levels often stem from faulty oxygen sensors, worn catalytic converters, or incorrect fuel mixtures. Given the age and low annual mileage, a physical inspection should also focus on structural corrosion on the sills and wheel arches, which often affects older Mercedes models regardless of distance driven. The suspension should be checked for seized bushes or perished bushings, common issues in luxury vehicles that remain stationary for extended periods.
