Mercedes-Benz A45 AMG S Plus

The A45 AMG S Plus represents the top of Mercedes-AMG's compact performance range, and this 2026 example has covered just 1,200 miles from new — for all practical purposes, a brand-new car, with the factory warranty intact until March 2029. Finished in Cosmos Black Metallic, it's a subtle but purposeful exterior choice that suits the sleeper credentials of the platform. One owner from new rounds out a provenance that's about as clean as a used car gets.

Beneath the bonnet sits AMG's hand-built 2.0-litre turbocharged four-cylinder — at 415 bhp, it holds the distinction of being the most powerful series-production four-cylinder engine in the world. Drive goes to all four wheels via AMG's 4MATIC+ torque-vectoring AWD system and a 7-speed wet dual-clutch gearbox, delivering a 0–62 mph time of 3.9 seconds. The S variant raises power over the standard A45 AMG by around 40 bhp, and the Plus trim adds further equipment over the base S.

Inside, the Two-Tone Titanium Grey Pearl and Black Leather with yellow stitching is a considered combination — the stitching colour echoes AMG's branding without tipping into ostentation, and the dual-tone leather lifts the interior above the standard A-Class it shares its shell with. At £54,995 with under 1,200 miles on the clock, it represents a meaningful discount to the new car price while retaining most of the warranty.
