Our Verdict
This 2005 Mercedes CLK with the 3.0-litr
Given that the mileage is well above what you would expect for a 2005 car, expect that wear items such as suspension bushes, brake discs, tyres and electrical components may soon need attention. The earlier MOT advisories relating to front wheel bearing play and front brake disc wear are worth investigating, as bearing replacement on a Mercedes of this age can be a moderately costly job. Ask the seller for any invoices for recent work and, if possible, a pre-purchase inspection by a specialist familiar with Mercedes vehicles of this era.
A CLK with the 3.0-litre V6 petrol engine is generally cheaper to maintain than the larger V8 variants, but parts are still Mercedes-priced compared with mainstream brands. Check that all electrical features work, including the roof mechanism if it is a convertible, the climate control, and the central locking, as these are common failure points. Negotiate on the basis that high-mileage German cars often need £500-£1,500 of work in the first year of ownership, and treat any service history paperwork as essential rather than optional.
The 3.0-litre V6 petrol engine typically returns around 25-30 mpg in real-world mixed driving, which is reasonable for a car of this size and age. Road tax for a 2005 petrol of this engine size is likely to fall in the higher bands, so check the current VED before purchase. Insurance for a Mercedes CLK tends to sit in groups 32-38 depending on the variant, so premiums may be notably higher than for a comparable Japanese coupé.
Routine maintenance such as oil and filter changes is straightforward, but Mercedes-specific items (sensors, suspension parts, electronic modules) can be expensive. A realistic annual running cost, covering fuel, tax, insurance and routine servicing with a modest allowance for wear items, is likely to be in the region of £1,800-£2,400 per year. Budget separately for the bigger-ticket items that often arise on cars of this age and mileage.
Focus first on the items flagged in the MOT history: the front wheel bearings noted as having slight play in 2022, and the front brake disc condition. Although the 2024, 2025 and 2026 tests were clean, a physical check of steering feel, brake pedal travel and any grumbling noises from the front wheels is sensible. Also inspect the bodywork carefully for rust, particularly around wheel arches, sills and the boot lid, as Mercedes of this era are known for corrosion in these areas.
Check the condition of the side repeater lenses and headlamp lenses, as these were flagged in 2023, and confirm all bulbs and indicators function correctly. Look for any signs of oil leaks from the engine and gearbox, which are common on higher-mileage Mercedes V6 units, and verify that the timing chain or belt (depending on service interval) has been replaced within the recommended schedule. Finally, a diagnostic scan with a Mercedes-capable tool can reveal hidden fault codes that an MOT cannot detect, particularly for the air suspension or ABC system if fitted, and the central electronics.
This silver Mercedes CLK, first registered in November 2005 and now showing 126,596 miles, has passed every MOT recorded in the past four years. The most recent three tests (2024, 2025 and 2026) were passed with no advisories at all, suggesting the car's recent record is relatively clean. However, the 2022 test recorded front wheel bearing play on both sides along with brake disc wear, and the 2023 test flagged minor lens issues, meaning a full picture of its current state requires a physical inspection. With no aggregate reliability data available for the CLK model, conclusions rest solely on this individual vehicle's history.
No aggregate MOT reliability data is available for the Mercedes CLK model, so any conclusions must rest on the individual vehicle's history rather than broader trend information.
