The Ostentatienne Opera Sedan was offered at a F.O.B. price of $19,600 (1967), had a weight of 5,740 lb (2,600 kg), and sat on a 119 in (3.02 m) wheelbase. Prices have also been quoted at $25,600. Tires for the vehicle were nitrogen filled 7.50”x20” (USA). The Ostentatienne was powered by an International Harvester truck engine.
Entry into the car was from the rear; solid steel side rails (designed to protect passengers during a crash) prevented doors along the vehicles sides. The Ostentatienne could be ordered customized to suit its buyer’s wishes; Ming styled oriental rugs, refrigerators and sealed beam taillights were some of the options available. Production is estimated at three to four vehicles per year.
