An exceptional, collector-standard Mercedes-Benz SLK 55 AMG, finished in Obsidian Black Metallic with Black/Anthracite Nappa leather. With just 18,200 miles recorded at its most recent service, an extensive Mercedes-Benz digital service history and remarkable overall condition, this is a truly outstanding example. The paintwork, cabin and presentation are of a standard rarely encountered, making this a particularly exciting opportunity for the discerning Mercedes-AMG enthusiast or collector. Built in May 2015 and registered in October 2015, this SLK 55 AMG is powered by AMG's hand-built 5.5-litre naturally aspirated M152 V8, complete with the engine-builder's signed plaque. Producing 421 bhp and 540 Nm, it offers effortless performance and a glorious eight-cylinder soundtrack, matched to the AMG SPEEDSHIFT PLUS seven-speed automatic transmission with steering-wheel paddles. A thrilling and increasingly distinctive AMG driving experience. Its specification is equally impressive. The Obsidian Black coachwork is complemented by factory-option 18-inch AMG multi-spoke alloy wheels, striking gold-finished brake calipers, drilled front brake discs, AMG aerodynamic styling, boot-lid spoiler and the distinctive AMG GT-inspired vertical-slat front grille. The electrically retractable panoramic glass Vario-roof makes this an equally rewarding roadster with the roof up or down. The beautifully preserved interior features Black/Anthracite Nappa leather AMG sports seats with contrasting stitching, electric adjustment and three-position memory, heated seats, AIRSCARF neck-level heating and lumbar support. Further highlights include the AMG Performance steering wheel with DINAMICA grips, black ash wood trim, aluminium roll-over-bar inserts, Harman Kardon premium surround sound, COMAND satellite navigation, Bluetooth telephone and audio streaming, DAB radio, USB/media interface, DVD playback, dual-zone climate control, front and rear PARKTRONIC with Parking Guidance, Intelligent Light System headlamps, automatic high beam, LED daytime running lights, traffic-sign recognition, folding and auto-dimming mirrors, rain-sensing wipers and AMG floor mats. The Mercedes-Benz digital service history is a real highlight, with ten recorded entries and an extensive accompanying file of invoices and supporting documents. The first service was carried out in November 2016 at 3,062 miles, followed by April 2018 at 9,396 miles, March 2019 at 9,606 miles, April 2020 at 11,796 miles and December 2021 at 15,219 miles. The consistently documented mileage progression reflects its remarkably light use. In March 2023, at 16,056 miles, the car underwent a comprehensive Service B, including renewal of all eight spark plugs, engine oil and filter, air and cabin filters and brake fluid. Further recorded servicing followed in April 2024 at 17,514 miles and June 2025 at 17,707 miles. In July 2025, at just 17,773 miles, the seven-speed automatic transmission oil and filter were replaced, a particularly worthwhile maintenance item on a performance AMG. Most recently, Mercedes-Benz Birmingham carried out a Service A and brake-fluid replacement in May 2026 at 18,200 miles, alongside a Mercedes-Benz vehicle health check. This recorded approximately 7mm of tyre tread and 8mm brake-pad thickness at both axles, further complementing the car's excellent presentation and careful maintenance. It is the combination that makes this SLK 55 AMG so special: the naturally aspirated hand-built V8, exceptionally low mileage, desirable specification, meticulously documented Mercedes-Benz service history and genuinely exceptional cosmetic condition. A collector-quality example that stands apart from the ordinary and must be viewed to be fully appreciated.
