The MERCEDES-BENZ E CLASS COUPE & CABRIOLET (2017-20) E400 4MATIC 2DR CABRIOLET 2.9D DPFR SS 340 EU6 AMG LINE PREMIUM 9G-T+ AUTO is a large, premium four-seat convertible, aimed at buyers wanting open-air motoring with executive-car comfort rather than everyday hatchback practicality. In the UK market, it sits above mainstream cabriolets, competing with the BMW 4 Series Convertible and Audi A5 Cabriolet. Checks on mycarcheck.com show 87 look-ups covering 27 different cars, a useful sample for this relatively specialised model. Recorded examples averaged £39,700, 26,000 miles and around 5,000 miles a year, with just over one previous keeper on average. These figures suggest low-mileage, carefully owned examples are common in the checks, though individual histories vary. The E400 4MATIC suits couples or small households seeking a commuter and tourer, with all-wheel drive, strong performance, a folding roof and AMG Line trim. It feels special compared with rivals, but running costs are higher.
