Entry-level AMG Line gets plenty of kit including 19in alloy wheels, air suspension, keyless entry and start, metallic paint, adaptive LED headlights, front and rear parking sensors, a reversing camera, soft-close doors and a powered boot lid. Step inside and you’ll find nappa leather covering the heated front and rear seats, with full electric adjustment, including lumbar support, up front. Then there's the four-zone climate control, the nine-speaker stereo, the 12.3in digital driver’s display, the 12.8in infotainment system with wireless smartphone charging and the 64-colour ambient LED lighting. We'd go for the next model up, though, which is AMG Line Premium. It adds the option of the long wheelbase, plus electrically operated and cooled rear seats, a panoramic sunroof, a 360-deg parking camera and a 710-watt/ 15-speaker Burmester sound system.
