race at the 24 Hours of Le Mans, the car was completed in 1966 and named the 400 GT Monza. The original name was the "400 GT Neri and Bonacini," but the final name Monza was eventually chosen due to its brevity and evocation of racing history. The aluminum body was hand built in the Neri and Bonacini shop and went through many revisions during the fabrication process. The final result was a distinctive fastback, with a long hood and Kamm tail. The designers integrated a roll bar into the extremely thick C-pillar, possibly increasing roll-over safety but compromising rearward visibility. Other details included a very low and raked windshield, prominent but non-functional air vent grilles behind the front wheels and stylized "400 Monza" badging. Overall, the design shows visual similarities to other contemporary Italian sports cars such as the Bizzarrini 5300 GT and the Lamborghini Miura. Homologation problems prevented the car from ever racing and the American customer who commissioned it apparently never received the car. It was instead displayed at the 1967 Barcelona Motor Show on the Lamborghini importer Amato's stand. A wealthy Spaniard purchased it at the show and the 400 GT Monza remained in his family after his death in the early 1990s. In 1996, auction house Brooks (now Bonhams) discovered the car in storage when they were contacted by the family of the now deceased owner to appraise some other cars. After nine years of negotiations, the car was finally sold at Bonhams' December 2005 auction in London for £177,500 GBP.
