Nadeau Bourgeault built his car in Sausalito, California in 1958, making it one of the earliest mid-engine cars built on the West Coast. Bourgeault had been the body shop manager for British Motor Car (BMC) Inc. in San Francisco and while there worked with Joe Huffaker on the first front-engine BMC Formula Juniors, but left after only a few of the BMCs were built. Nadeau relocated to Bill Breeze’s Sports Car Center (SCC), located off Highway 101 north of Sausalito in a complex of WWII-era Quonset huts. Bill Breeze, the SCC owner was a contemporary of Phil Hill and had raced in Jaguar 120s and C types before he was injured in a crash. The SCC played a vital role in the growth of sports car racing in Northern California – it offered access to professional, knowledgeable businesses where racers got advice, parts, service, race preparation, or even a race car. The Sports Car Center was the forerunner of the many shops that would spring up around the San Francisco Bay Area, and included two young mechanics, one named Bob Winkleman, who later built the Winkleman Formula Fords and another named Peter Brock, later of Cobra and Datsun racing fame. The importance of the SCC was reflected when Breeze was inducted into the 2010 SCCA San Francisco Region Hall of Fame.
After leaving BMC, Nadeau set up shop in one of the SSC Quonset huts, a body and fender shop that specialized in aluminum repairs and re-bodies, and made his living designing and building sports cars, fixing race car problems and maintaining customer cars. One of his first customers was Nick Reynolds of the Kingston Trio, who had an older Ferrari 166 Milla Miglia. The Kingston Trio had started as a San Francisco nightclub folk band, and achieved worldwide wealth and fame. With his money, Reynolds was able to indulge his interests, and became a serious sport car enthusiast. With backing from Reynolds, Bourgeault built his 1.1-liter Fiat-powered Formula Junior, which Nick Reynolds drove in competition. The Bourgeault Formula Junior machine was later featured in an article in the August 1961 issue of Car & Driver magazine. Bourgeault later built several other unique machines, a couple of Formula B machines and a sports racer fitted with a BRM Formula 1 engine before dying of a heart attack in 1974. Unfortunately, all of Bourgeault’s remaining drawings and one of his small-bore sports racing cars were lost in the Oakland Hills firestorm in 1991.
Simon Favre first saw the Bourgeault Formula Junior machine at a classic car dealership, and claimed it was love at first sight, but he purchased the car later in its current state in 1993 from Al Santos. The car features a 1.1-liter Fiat engine coupled to a VW transaxle and uses Fiat brakes. Favre attends about four vintage events a year with his unique car.
