Launched at the 1975 Paris Motor Show as a replacement for the outgoing Dino 246 GT, the Scaglietti-built Ferrari 308 GTB featured a mid-mounted 2.9-litre V-8 engine coupled to a five-speed manual gearbox.
The earliest and more desirable examples were bodied in glass-reinforced plastic as an alternative to their later, steel-bodied counterparts. Among those to see the 308 GTB’s competitive potential were Italian brothers, Carlo and Giuliano Facetti from Bresso, who converted four examples to Group 4 specification. Their 308s became famed for their rarity and pre-date the Michelotto-built Group 4 and Group B cars that emerged in the early-1980s.
This Ferrari 308 GTB, chassis 18855, left the factory in early 1976 finished in Rosso Chiaro, and was delivered new to a dealer in Bolzano, Italy. By 1977, the Facetti brothers had acquired the Ferrari, and converted it to Group 4 specifications. For its first outing, the car was entered into the 1978 24 Hours of Daytona, driven by Bob Bondurant, Dino Mallet, Romeo Camathias, and Sergio Rombolotti. They qualified in 32nd place, but—due to alternator failure—the car was forced to retire after 82 laps.
Following Daytona, chassis 18855 was fielded in the 1978 Campionato Italiano Gruppo 4. Piloted by Carlo Facetti—making this the only Facetti-built 308 to be driven by Carlo—the Ferrari was immensely successful. Facetti found success early in the season, taking victory at the Autódromo dell’Umbria in the fourth round of the championship. His winning ways continued in rounds five and six, finishing 1st at both the Misano World Circuit and at the Autódromo de Pergusa. For the seventh round of the championship, at the Giro d’Italia, Facetti opted to field his Porsche 935 in Group 5 rather than his 308, and he finished 2nd overall. For the eighth and final round at Vallelunga, Facetti reprised chassis 18855, heading the pack in Group 4 and confirming his position as 1978 Campionato Italiano Group 4 Champion.
The hotshoe returned to the championship in 1979 for the 6 Hours of Mugello. Though the Ferrari was initially entered into the event, Facetti contested the race in his Porsche, again bringing the 935 home in 2nd. The Ferrari’s next outing took place on 27 May at Havířov International; despite strong qualifying that saw him start the race from the front row, an accident on the fourth lap forced the 308’s retirement. Entry lists and period photographs on file show that the car also raced at the Autodromo Nazionale di Monza and Vallelunga Circuit later that year, though the results of each race are unknown.
By mid-1980, the 308 GTB had been sold to Ciro Nappi, the founder of Scuderia Vesuvio. On 5 October, Sergio Romboloti—who was a listed driver for the car at its 24 Hours of Daytona debut—raced the car in the Trofeo Leopoldo Carri at the Autodromo Nazionale di Monza. Nappi would go on to race the Ferrari at Vallelunga twice the following year, winning his class on 18 October. Ciro and his brother Piero continued to compete with the car, finally selling the Ferrari to the consigning owner in 2018, following 38 years of ownership.
With the ‘Vetroresina’ body well-preserved, the owner opted to have chassis 18855 mechanically restored shortly after buying the car. The engine and gearbox were rebuilt by the Ferrari specialist, Roelofs Engineering in the Netherlands, with the suspension and other components restored in Belgium by Gipimotors. The restoration adhered to Group 4 FIA regulations and in October 2018, an FIA Historic Technical Passport was issued. Invoices on file for the restoration work exceed €200,000.
Following its restoration, this storied 308 has been driven at three test days but is yet to have raced. At an Automobil Club Tazio Nuvolari event, the Ferrari was reunited with not only another vanishingly rare Facetti-built 308, but also its creator and former driver, Carlo Facetti. The 308 is also mentioned in the racer’s book, Potenza in punta di piedi.
The car is accompanied by historic photographs, old race entry sheets, and sits on new Gotti wheels and tyres. It is offered with six spare Gotti wheels and tyres, as well as four period-correct BBS wheels, alongside a selection of gearbox components.
Chassis 18855 presents a wonderful opportunity to acquire one of just four Facetti-built 308 GTBs. With an enviable period race history and eligibility for leading historic motorsport events including the Modena Cento Ore, Targa Florio Classic, and Tour Auto, this rare and well-preserved Ferrari is the perfect tool for regularities and rallies.To view this car and others currently consigned to this auction, please visit the RM website at rmsothebys.com/en/auctions/pa23.
