The MERCEDES-BENZ E CLASS COUPE & CABRIOLET (2017-20) E400 4MATIC 2DR COUPE 3.0 V6 SS 333 EU6 AMG LINE PREMIUM 9G-T+ AUTO is a premium, two-door grand touring coupe: more style-focused than an E-Class saloon, and roomier and more refined than a compact sports car. In the UK, it sits in the executive-coupe market alongside cars such as the BMW 4 Series and Audi A5. The mycarcheck.com sample includes 353 checks covering 114 different cars, a useful snapshot rather than a measure of every E400. Checked examples averaged 35,000 miles, around 6,000 miles a year, and nearly 1.7 previous keepers; the average private-sale valuation was £27,700. These figures can help set expectations, but condition and history still matter. With its V6, four-wheel drive and smooth automatic, it delivers brisk, assured cruising and a sporty, well-equipped feel. It suits couples seeking comfort and presence, though rivals may be cheaper to run.
