Michelotto 308 GT/M. Full s/n EF001. A prototype built by Auto Sport, Michelotto and Ferrari in 1983 for test and research purposes for the 288 GTO and later, the F40 series. Later sold to Garage Francorchamps for Belgian real estate and construction billionaire, race driver and collector Jean Blaton, aka Beurlys:

Jean Blaton, Belgian billionaire, ex-race driver, multiple Le Mans entrant in the 1950s and 1960s, used alias name "Beurlys" when racing. Jean Blaton was the main supporter of Garage Francorchamps/Ecurie Francorchamps. Used to own a big car collection, many cars were quietly sold off (due to his age and failing health) in the late 1990s.

S/n EF001 was the first of three 308 GT/M's built by Michelotto in 1982-85. Michelotto had a good degree of Ferrari factory input to the design and development work. GT/M's were experimental prototypes ultimately derived from the 308, but used a specially constructed tubular chassis fabricated by Auto Sport of Bastiglia. Work began in late 1982 with the chassis/car built around a longitudinally mounted engine.

Ferrari adopted the longitudinal layout for their subsequent 288, F40 and 348

The 308 GTB/M IMSA was to compete in the Group B rally class. The 308 GT/Ms main claim to fame is that it was designed from the start to be a pure race and rallye car, has a prototype status, light weight and aerodynamic styling, which evolved from the 512 BBLM and later evolved into the F40. The 308 GT/M IMSA was built purely as Group "B" rallye cars but Michelotto and Ferrari miscalculated the moment - 4-wheel drive became all the rage. The Ford Escort 1700T was another such manufacturer miscalculation.

They were called IMSA out of respect for the stability of the IMSA series technical regulations. Rule stability was a pointed comment that Enzo Ferrari wanted to make at that time!
