spring of 1968, Peter Monteverdi considered a significant increase in annual output; Around 100 vehicles were planned per year. These numbers did not match the capacity of Atelier Frua, whose bodies were purely hand built, and who had no capacity to build such high numbers of vehicles. Frua then suggested outsourcing the production to Carrozzeria Maggiora, where some Maserati models were already built and capacities for a partially automated production existed. But Monteverdi rejected this step, because it was associated with high investments, especially for pressing tools. Instead, he was looking for another body shop that could do the purely manual production of the desired quantities. This he found in Carrozzeria Fissore in Savigliano near Milan, a smaller and less prestigious design studio of the northern Italian level, which in the 1960s designed the De Tomaso Vallelunga and some DKW models for the South American market. From the summer of 1968 Monteverdi had a total of about ten bodies of Pietro Frua's design, produced at Carrozzeria Fissore. At the same time Peter Monteverdi denied the payment of royalties to Frua, whereupon this Monteverdi had the use of his design prohibited by court order. Monteverdi then had to design a new body, which was available in 1969. Until then, Monteverdi could not sell off all the bodies built by Fissore in Frua style; The last of these rare models were sold off in 1973. Pietro Frua used the basic features of the Monteverdi 375 in a modified form also in later other designs. So in 1971 he designed a fastback coupe based on the Dodge Challenger , which repeated many features of the 375. The Challenger Coupe still exists today and is regularly shown at European exhibitions. The Fissore Models For 1969 Monteverdi had to put as a consequence of the lawsuit with Frua a new body for his coupe on the legs. On the occasion of this new beginning, Monteverdi changed his concept. Unlike before, the pure two-seater should not be the volume model; Rather, various inquiries from prospective buyers had revealed that a 2 + 2 coupe on extended chassis was preferred. Accordingly, the High Speed 375 L should be the base vehicle of the Monteverdi range. In the next eight years, the bodies were to be produced predominantly, but not exclusively, at Fissore in Savigliano. Monteverdi 2000 GTI The 2000 GTI study was designed as a cheaper alternative
