Our Verdict
Proceed with caution due to high mileage
Given the high mileage of 165,343 miles, your primary focus should be on verifying the service history to ensure the large 3.5L engine has received regular oil changes. Ask the seller for evidence of any major component replacements, such as suspension elements or cooling system parts, which are common maintenance items on older Mercedes models.
When viewing the car, check for any signs of fluid leaks around the engine bay and ensure the gearbox shifts smoothly through all gears. Because the 2023 MOT failure involved a fractured coil spring, it is worth asking if the suspension has been fully inspected or overhauled since that repair was made.
Running this 3.5L petrol engine will involve relatively high fuel costs compared to modern counterparts, as larger displacement engines typically consume more fuel, especially in urban driving. You should also factor in a higher insurance group, which is common for Mercedes-Benz coupes of this era.
Maintenance costs for a vehicle of this age and mileage can be unpredictable. While the MOT history shows no recent defects, larger mechanical repairs on a premium brand can be costly. Expect an estimated annual running cost in the region of £1,800-£2,400, depending heavily on your annual mileage and insurance profile.
Specifically inspect the suspension components. The MOT history shows a failure in July 2023 due to a fractured offside rear coil spring; ensure that the current suspension feels firm and does not produce knocking sounds over bumps.
Additionally, check the condition of all rubber seals and hoses. Although the last three MOTs recorded no defects, high-mileage vehicles often develop minor leaks or wear in the cooling system that may not yet have triggered an MOT failure. Check the tyres and brake pads for even wear, as these are common items that can lead to future MOT advisories.
This 2008 Mercedes CLK is a high-displacement 3498cc petrol model with 165,343 miles recorded at its last MOT in July 2026. While the mileage is significant, the vehicle has maintained a clean MOT record since a single failure in 2023. The lack of recorded defects in the most recent three tests suggests a period of stability in its mechanical compliance.
No aggregate reliability data is currently available for the Mercedes CLK to provide a specific trend analysis.
