Even though it is a large, elegant car, Touring's Superleggera (super-light) body construction allowed their 2900s to be highly competitive road racers.
A very fine example of this rare car can be found in Naples, Florida at the Revs Institute Collier Collection. The museum's background information on the car is here.
Alfa Romeo 8C 2900 at Pebble Beach Concours, 2007. When taking this photo I hadn't yet developed the habit of photographing information plaques, so I don't know for sure exactly what model this is. However, it does look a lot like our subject car, but perhaps a Corto (short wheelbase) version.
