2020 Mercedes-Benz SL 400 Grand Edition

The R231 SL400 represents the closing chapter of Mercedes' long-running SL formula — a biturbo V6 grand tourer with a retractable hardtop, genuine performance credentials, and a cabin that still feels contemporary. This 2020 example shows just 9,082 miles, exceptional for a car now over five years old and suggesting it has spent much of its life garaged rather than driven. Finished in White with the Grand Edition trim, it comes well-specified: the Premium Equipment Line adds a premium sound system, the Night Package darkens the exterior brightwork, and Active Park Assist with Parktronic and a reversing camera round out the convenience features.

The 3.0-litre biturbo V6 produces 362 bhp and pulls to a governed 155 mph, with 0–62 mph dispatched in 4.9 seconds through Mercedes' nine-speed G-Tronic+ automatic. This sits in the practical middle of the SL range — more characterful than the entry-level four-cylinder, without the focused edge of the AMG variants — making it the most rounded daily-usable choice in the lineup.

As one of the final R231 models before the R232 generation arrived and fundamentally changed the SL's character, this is increasingly a car that rewards buying sooner rather than later. Near-new mileage and a solid factory options list make this one of the more complete examples currently on the market.
