The 1956 Maserati A6G/54 coupe, chassis 2181, is the sole surviving example of two third-series cars bodied as coupes by Pietro Frua, making it unique among the model's limited production run of 65 cars. First exhibited at the 1956 Turin Auto Salon, it was originally dispatched to a Maserati importer in San Francisco and later passed through several American owners before undergoing a comprehensive restoration in Germany circa 2007–2011. Fitted with a correct period twin-cam engine and authentic components, it won its class at the 2014 Pebble Beach Concours d'Elegance during the Maserati Centennial celebration.
