2004 Mercedes-Benz SLK 3.5L Petrol · YY54 OPO

The 2004 Mercedes-Benz SLK presents a broadly stable roadworthiness picture based on its most recent test. The December 2021 examination at 158,061 miles returned a pass with no defects recorded, though the DVSA log also shows a failed attempt on the same date with no defects listed, a clerical or administrative anomaly rather than a mechanical fault. Across the five available tests from March 2018 to December 2021, the vehicle cleared every examination without advisories, indicating no worsening trend in suspension, braking, or structural condition over that window. The mileage record shows light-to-moderate use for a 22-year-old car. The odometer read 144,041 miles in March 2018, then 152,209 by February 2019, 156,683 in December 2020, and 158,061 in December 2021. That equates to roughly 3,500 to 4,600 miles per year across those intervals, below the 7,185 annual average implied by the total. The sparse history, with only five tests over four years and a near 22-month gap between the 2019 and 2020 entries, gives limited visibility but no recorded wear-driven failures. A buyer should still commission an in-person inspection of consumable and age-sensitive components not captured by a clean MOT. At 158,061 miles and 22 years old, suspension bushes, coil springs, and brake discs will likely show fatigue even if the tester raised no advisory. The same applies to underbody corrosion and exhaust emissions integrity, both common on early SLK models left through damp winters. The duplicated 10 December 2021 entries at identical mileage warrant a DVSA data check to confirm which result stands. Beyond that administrative query, the absence of recurring faults suggests previous owners kept basic upkeep current, though the thin test frequency means latent wear could exist unseen.
