2019 Mercedes-Benz SL SL500 AMG Line Premium

The SL500 sits in the final years of the R231 generation, which swapped the old folding hardtop's glass for a panoramic Vario-Roof that can be switched between tinted and clear at the touch of a button. Under the bonnet is the 4.7-litre twin-turbocharged V8, producing 449 bhp and 700 lb-ft, with a 155 mph limiter and a claimed 0-62 mph time of 4.3 seconds. Power goes through the nine-speed G-Tronic+ automatic to the rear wheels.

This 2019 (69-plate) car has covered 32,998 miles and is finished in Brilliant Blue, a factory paint option. It is in AMG Line Premium trim, which brings keyless entry, a premium branded audio system, Active Park Assist with front and rear sensors, Apple CarPlay integration and automatic headlights. The Euro 6 V8 is a relaxed grand tourer first and a sports car second, but the combination of effortless torque and a usable boot makes it a quick and capable long-distance convertible.
