      Manager's comments

      Paul Morris, General Manager
      Paul Morris, General Manager,

      Mercedes-Benz of Beaconsfield

      "This stunning 2020 Mercedes-Benz C300 AMG Line (Premium) Cabriolet is a true celebration of style, sophistication and open-top motoring. Finished in Brilliant Blue Metallic with a contrasting Dark Blue Soft Top, it delivers the perfect mix of elegance and excitement. Having had just two owners and boasting a full Mercedes-Benz service history, most recently completed in October 2025, this car has been cherished from day one. Under the bonnet lies a smooth yet spirited 2.0-litre petrol engine with EQ Boost technology, delivering an impressive 258 horsepower with remarkable refinement and efficiency. The G-Tronic+ automatic gearbox ensures every gear change is seamless, while the combination of AMG-tuned suspension and 19-inch AMG alloy wheels gives it superb road manners, whether cruising the coast or gliding down the motorway. Inside, luxury takes centre stage. Porcelain heated leather seats cocoon you in comfort, while AIRSCARF neck-level heating and the innovative AIRCAP wind deflector make roof-down driving a year-round pleasure. The COMAND Online navigation system, Apple CarPlay and wireless charging keep you seamlessly connected, while the 12.3-inch digital display ensures all vital information is crystal clear. Every journey feels effortless, intuitive and indulgent. When it comes to safety, Mercedes-Benz delivers excellence. The MULTIBEAM LED headlamps adapt to the road ahead for optimum visibility, and the reversing camera makes parking stress-free. Add in the intelligent driver assistance systems and you have a cabriolet that's as reassuring as it is rewarding. Buying from Vertu Mercedes-Benz Beaconsfield means peace of mind as standard. Every car is thoroughly inspected by manufacturer trained technicians and includes a comprehensive warranty for total confidence. You are not just buying a car you are investing in an experience backed by Mercedes-Benz expertise and exceptional customer care. The C300 AMG Line Cabriolet combines power, poise and precision in a way few rivals can match."
