Our Verdict
Proceed with caution but consider this a
When inspecting this specific CLK, pay close attention to the suspension components. The March 2026 MOT recorded worn suspension arm pins or bushes on both the nearside and offside front, which can affect handling and cause knocking noises. You should also check the current condition of all four tyres, as the most recent record indicated wear close to the legal limit on both the nearside rear and offside front.
Given the vehicle's age and mileage, verify that any recent work to address the suspension advisories has been completed with receipts. Ask the seller for evidence of recent tyre replacements to ensure the vehicle meets safety standards beyond the advisory stage. While the 1.8L petrol engine is a common variant, ensure the service history is documented to support the vehicle's longevity.
Running costs for this 1796cc petrol Mercedes will be influenced by its age and luxury positioning. Expect moderate fuel economy typical of a 2003 executive coupe. Tax and insurance groups for this model vary depending on specific trim levels, but buyers should budget for higher-than-average insurance premiums compared to standard hatchbacks.
Maintenance costs may fluctuate due to the age of the vehicle; while the MOT history shows no major failures, the recent advisories for suspension and tyres suggest that routine wear-and-tear items will require regular investment. An estimated annual budget should account for these mechanical upkeep requirements alongside standard servicing.
Focus your physical inspection on the front suspension area. The 2026 MOT specifically flagged worn suspension arm pins or bushes on both the nearside and offside front; listen for clunks or knocks when driving over uneven surfaces or turning the wheel.
Additionally, inspect the tread depth and condition of all four tyres. The MOT history has repeatedly highlighted tyre wear issues, specifically on the offside front in 2024 and both the nearside rear and offside front in 2026. Check for uneven wear patterns, which could indicate alignment issues related to the previously noted suspension wear.
This 2003 silver Mercedes CLK has covered 125,130 miles since its first registration in September 2003. The MOT history shows a pattern of passing, with the most recent test in March 2026 noting several advisories regarding suspension bushes and tyre wear. The mileage has increased steadily, averaging roughly 3,000 to 4,000 miles per year over the last few recorded tests.
No aggregate reliability data is currently available for the Mercedes CLK to provide a statistical comparison.
