The MERCEDES-BENZ E CLASS COUPE & CABRIOLET (2017-20) E400 4MATIC 2DR COUPE 2.9D DPFR SS 340 EU6 AMG LINE PREMIUM 9G-T+ AUTO is a refined, powerful diesel grand tourer rather than an everyday hatchback. In the UK, it sits among premium executive coupes, pairing Mercedes-Benz comfort with a sleek, sporty look and four-seat practicality. Mycarcheck.com recorded 45 look-ups across 18 distinct VINs, a useful snapshot, though not every car. Checked examples averaged £31,800 in private-sale value, 50,000 miles and 11,000 miles a year; previous keepers averaged about 1.7. These figures set expectations, but each car’s history and condition matter before making your buying decision. Four-wheel drive and strong performance make it a confident, comfortable choice for couples or professionals covering long distances. AMG Line styling gives it extra presence, while the automatic transmission eases everyday driving. It is less practical than an SUV or estate, and likely costs more to run than a mainstream coupe. Compared with the BMW 4 Series and Audi A5, it prioritises luxury and relaxed touring.
