1980s AMG Masterpiece | Collector’s Holy Grail | Motorsport Provenance

This AMG M117 4V engine is a rare, hand-built relic from AMG’s pre-Mercedes era, extracted from an authentic 1980s Mercedes-Benz C126 SEC AMG “Widebody” coupe. A symbol of AMG’s engineering brilliance, this engine transformed Mercedes’ luxury grand tourer into a 170+ mph autobahn predator. With only a handful ever produced, it represents the pinnacle of 1980s European tuning culture and is a crown jewel for collectors, restorers, or museums.
