As the only example ever made, the Commendatore 112i has been returned to its original glory by the manufacturer, after spending some time kitted out as a more standard road car, sans the single rearview mirror and racing wheels. Now back to 1993 specifications, it boasts Porsche Arctic Silver paintwork, specially-commissioned BBS wheels, and Recaro blue and black interior trim, as intended by the original designer. The piece de resistance is the M120 V12 engine under the rear gullwing cover, which is sourced from Mercedes-Benz. It’s the same motor found on the Pagani Zonda, and, much like other one-of-one speedsters like this Zonda Aether Roadster from the same auction house, it is expected to sell for millions.
