1999 Mercedes SLK 2.3L Petrol · GMR 413

The 1999 Mercedes SLK presents an exceptionally clean MOT record, with a clear and stable maintenance trend. The most recent test, conducted on 5 June 2026 at 38,248 miles, passed with zero defects. This flawless result is not an isolated event; it extends back through five consecutive annual tests, all of which recorded no advisories or failures. Such a consistent run strongly indicates a vehicle that has been diligently maintained and is currently in excellent mechanical order. The mileage pattern reinforces the picture of careful, limited use. Over approximately four and a half years, from the test in May 2022 at 35,681 miles to the June 2026 test at 38,248 miles, the car covered just 2,567 miles. This equates to an average of roughly 570 miles per year in that recent period, which is even lower than the vehicle's already modest lifetime average of about 1,417 miles per year. The annual tests show remarkably consistent, minimal accumulation, with the largest single-year jump being 604 miles between May 2023 and June 2024. There are no gaps or sudden spikes in the record to suggest neglect or prolonged storage. Despite the pristine paperwork, a physical inspection remains essential for a car of this age and low mileage. The complete absence of any suspension or braking advisories is unusual for a 27-year-old vehicle, so a thorough check of suspension bushes, coil springs, and dampers for age-related perishing is wise. Brake discs, calipers, and flexible hoses should be examined for corrosion and seizure from infrequent use. The exhaust system and its mountings, along with the condition of the tyres including sidewall date codes and tread depth, must be verified. Finally, a detailed inspection of the body structure, particularly the sills, subframes, and floor pan, is critical to confirm no hidden corrosion compromises the chassis integrity.
