Provenance and originality
For pre-war and vintage cars such as the Bugatti Type 57 / 57S / 57SC, provenance is paramount. Chassis and engine number matching, period coachbuilder records, factory build sheets where available, continuous ownership documentation, original handbooks and any competition or concours history are the foundation of value. Body style (Atlantic > 57SC > 57S > 57), originality of chassis-body pairing, Bugatti Trust documentation, and continuous history.
