The Boomerang was registered as a road car, but it was intended as a one-off show car. It was shown in dozens of places, and after the 1974 car show in Barcelona it was sold to a private individual. In 1990, it was shown at the Bagatelle Concours in Paris, 1993 Concorso Italiano, Carmel (Calf.) and Pebble Beach, with a new owner and some restoration work having been done. It made an appearance again in 2000 at the Monterey Historic Automobile Races, and Pebble Beach - 50th Anniversary -, 2012 "BEST OF SHOW", May, Monte Carlo, Monaco, 2013 "BEST OF SHOW", October, Knokke, Belgium, 2014 "Paris Motor Show". On 5 September 2015, the Boomerang was auctioned by Bonhams at the Château de Chantilly, France, and sold for €3,335,000 (approximately US$3.7 million).[3]
The Boomerang is powered by a 4.7L V8 engine producing 310 hp (314 PS; 231 kW) and 460 N⋅m (339 lb⋅ft) of torque, driving the rear wheels and mated to a 5-speed manual transmission. The interior features a unique dashboard layout where the steering wheel and gauge cluster are part of a single console that emerges from the dash, and the steering wheel rotates around the stationary gauges.
