About the Mercedes-Benz CLK
Produced from 1997 to 2010 across two generations, the Mercedes-Benz CLK bridged the gap between the C-Class and E-Class as an elegant two-door coupé and cabriolet. The first generation (W208, 1997-2002) offered models including the CLK200, CLK230 Kompressor, and high-performance CLK55 AMG. The second generation (W209, 2002-2010) introduced updated styling, improved build quality, and an expanded engine range including the CLK220 CDI diesel, CLK350, and the flagship CLK63 AMG with its 6.2-litre V8 producing 481bhp.
All CLK models featured rear-wheel drive, with most equipped with automatic transmissions. The cabriolet variants, introduced shortly after each coupé launch, featured a power-folding fabric roof. Build quality was generally excellent, with well-appointed interiors featuring leather upholstery, climate control, and comprehensive safety equipment including multiple airbags and ESP stability control on later models.
What Affects the Price of a Used CLK
Year and generation significantly impact CLK values, with W209 models (2002-2010) commanding higher prices than W208 versions due to improved refinement and more modern styling. Engine choice is crucial—AMG variants, particularly the CLK55 and CLK63, attract substantial premiums, whilst diesel CLK220 CDI models appeal to buyers seeking lower running costs. The CLK350 offers an excellent balance of performance and value.
Mileage heavily influences pricing, with sub-50,000-mile examples worth considerably more than high-mileage cars. Full Mercedes-Benz service history adds significant value, as maintenance costs can be substantial. Specification matters, with Avantgarde and AMG styling packages, panoramic roofs, COMAND navigation, and heated seats all desirable. Cabriolet models typically command £2,000-£4,000 more than equivalent coupés. Condition is paramount—any evidence of rust, particularly around rear wheel arches and sills, will significantly reduce value.
Used CLK Buying Tips
Inspect thoroughly for rust on both generations, focusing on rear wheel arches, front wings, and sills—corrosion can be expensive to rectify properly. Check the roof mechanism operates smoothly on cabriolets, listening for unusual noises, and ensure the rear window remains clear without delamination. Supercharged Kompressor engines (CLK200K, CLK230K) can suffer from worn supercharger bearings, causing whining noises.
Verify comprehensive service history with evidence of regular oil changes, particularly on AMG models. The SBC (Sensotronic Brake Control) system on 2002-2005 W209 models has a limited lifespan and replacement costs around £1,500—check service records for replacement evidence. Test all electrical functions including seats, windows, and climate control, as faults can be costly. Ensure tyres match across axles and check for uneven wear indicating suspension issues. A pre-purchase inspection by a Mercedes specialist is strongly recommended, particularly for AMG variants.
