Used Mercedes SLK

If you’re after open-top motoring in a car that’s easy to live with, the SLK stands out – bringing a bite of Mercedes luxury to your daily drives. Launched in 1996 and running through three generations before evolving into the SLC in 2016, it was designed to combine sporty looks with everyday comfort and usability rather than chasing the sharpest handling. Successive generations improved refinement, added more technology, and expanded the engine range – including a diesel in the final SLK line-up. Against rivals like the BMW Z4, Audi TT and Porsche Boxster, the SLK stands out for its luxury touches and everyday convenience while still offering wind-in-your-hair fun. Equipment levels are generous, with thoughtful touches like the Airscarf neck-level heater and a decent boot for a roadster. Practicality and running costs have improved through each generation, appealing to drivers keen on top-down thrills without sacrificing comfort or reliability.

Pros

Clever folding metal roof
Comfortable for long trips
Premium Mercedes interior

Cons

Limited rear visibility
Only two seats and a modest boot
Some rivals are more engaging to drive

What are the key safety features of the Mercedes SLK?

Every Mercedes SLK comes with stability and traction control, ABS and front and side airbags. More recent models also feature tech like rollover protection and tyre-pressure monitoring as standard, with options including advanced headlights and parking sensors.
What engine options are available with the Mercedes SLK?

The SLK offers a wide range of engines across its generations. Older models feature petrol units from 1.8 to 3.2 litres (often supercharged), while later models (2011-2016) include downsized turbocharged petrols and a diesel (2.1 CDi) for the first time. Enthusiasts might look for the powerful SLK 55 AMG petrol V8, but most buyers opt for the efficient SLK 200 or the mid-range SLK 250 variants.
What are the standard technology and infotainment features in the Mercedes SLK?

You’ll typically find air conditioning, electric windows and a quality audio system across the range. Meanwhile, later models include Bluetooth, navigation, DAB radio and USB connectivity. Look out for heated seats, the unique Airscarf neck heating system and sophisticated roof glass (Magic Sky Control) in the latest versions.
What is the fuel consumption of the Mercedes SLK?

Economy depends on the engine and year. The 2.1-litre diesel in third-generation cars can reach up to 56mpg (official figures), while the SLK 200 petrol is often close to 40mpg. Older V6 or V8 models will be thirstier, often returning between 25-32mpg in real-world use. It’s worth considering your expected mileage and fuel type when choosing.
What should I check when buying a used Mercedes SLK?

Inspect the roof for smooth operation – faults can be costly. Watch out for signs of water leaks, worn seals and rust (around wheel arches and subframes in older cars). Make sure you see a full service history and check the electronics, especially central locking and windows. For extra peace of mind, book a comprehensive check with The AA Vehicle Inspection.
Are Mercedes SLK cars reliable?

Reliability is generally good, especially with regular servicing. Most issues are related to the complex roof or age-related rust in early cars. Diesel and petrol engines are strong if maintained, but always check timing chains and make sure service intervals have been followed. Well-cared-for SLKs will reward you with years of enjoyable, low-stress ownership.
