Used Mercedes CLS for sale

The Mercedes CLS comes well equipped with safety features like automatic emergency braking, active lane-keeping, traffic sign assist and multiple airbags. Later models share safety tech with the E-Class, which holds a five-star Euro NCAP rating, giving you added peace of mind.

Depending on the generation, you’ll find a range of options – from efficient four-cylinder diesels (220d, 250 CDI) to strong V6 diesels (350 CDI, 400d) and petrol V6s. AMG variants bring V8 power for serious performance. Most UK buyers tend to favour diesel models for their balance of power and fuel economy.

On most models, you'll find sat nav, DAB radio, Bluetooth, heated leather seats and dual-zone climate control as standard. Later versions add widescreen digital displays, smartphone mirroring (Apple CarPlay and Android Auto) and enhanced driver-assist systems on higher trims.

On paper, the Mercedes CLS’s four-cylinder diesel models (like the 220 d or 250 CDI) are listed around 55–56 mpg (WLTP). In real-world UK driving, the average is closer to 40 mpg. If you’re eyeing a V6 diesel, expect real-world figures around 35–40 mpg. Petrol engines will be thirstier – mid-30s for V6s and around 25–28 mpg for V8 AMGs, depending on your driving style.

Check that major recalls, like injector replacements on some early diesels, have been done. Make sure all electronics work, especially the infotainment and phone pairing. Air suspension (if fitted) is great for comfort, but can be costly if it fails. For peace of mind, consider The AA Vehicle Inspection before buying.

The Mercedes CLS is generally praised for its solid build and dependable performance. While some owners have reported minor electrical or infotainment issues, major problems are relatively rare. Mercedes doesn’t always rank at the top of reliability surveys, but many drivers are satisfied with their cars and enjoy trouble-free ownership when the vehicle is well-maintained.
