to complete the unfinished design and build prototype bodies. The prototype was displayed to the public at the 1966 Italian Grand Prix at Monza. As many as 5 Iso Daytonas were built and details around their production history and specifications are unclear. One car of this type was showcased in the August 1966 issue of Road and Track, under the name "Nembo II." The magazine represented this car as derived from Bizzarrini's Iso Grifo and 5300 GT designs but does not mention any official connection with Iso. An Iso Strale Daytona 6000GT prototype sold at RM Sotheby's 2010 Monterey auction for $522,500, including buyer's fee. According to the RM Catalogue, this car was based on a crashed Iso Rivolta and was commissioned by Carlo Bernasconi of Milan, who directed Neri and Bonacini to rebody the car with his own design. The relationship between this car and the Bizzarrini/Rivolta Daytona design is unclear. A possible precursor to the Iso Daytona was the 1965 Bizzarrini "Nembo," featured in the May 1966 Road & Track issue. Designed by Bizzarrini and finished by Neri and Bonacini, it was nearly identical to an Iso Grifo but used a 7-liter Holman Moody-prepared Ford V8 engine. The subsequent history of this car is unknown. Road cars Ferrari Nembo The Ferrari Nembo cars were a series of rebodied Ferrari sports cars built by Neri and Bonacini in collaboration with American designer Tom Meade. Three Nembo spyders and one Nembo coupe were built, all based on 250 GT chassis and engines. Like all Neri and Bonacini-bodied cars, they were individually hand-built and differed in many details. The first Nembo spyder used a 1960 250 GT Coupé donor car (chassis 1777GT) and was built in 1965 for Meade's customer Sergio Braidi. Bradi wanted an open spyder-bodied car inspired by the 1964 series II 250 GTO, and initially proposed using a GTO chassis. Meade convinced Bradi to use the longer 250 GT chassis as he believed the extra length would result in a more harmonious design. The final steel bodywork was reminiscent of both the Series II 250 GTO and the 275 GTB/4 NART Spyder. The car was originally painted a very dark blue, almost black. Immediately following completion of the first Nembo spyder, a Nembo coupe was constructed using a 1959 250 GT PF Coupe donor (chassis 1623GT). The aluminum notchback body somewhat resembled a 1964 250 GTO, due in
