Monteverdi High Speed 375, a grand tourer meant to tackle Ferrari head-on while armed with 440s and 426 hemis, a simple chassis, and a glove box full of dreams.

Monteverdi's father grew his business into a major automobile dealer. 

A partnership with Ferrari was eventually secured, along with working relationships with Lancia and BMW. 

Peter helmed the dealership business, with his father acting as a sort of overseer, despite the business being largely run on his own capital. However, Monteverdi was cast out of Ferrari's inner circle after failing to pay for a 100-car inventory shipment to his dealership, angering Enzo Ferrari himself.

So, instead of trying to repair his relationship with Ferrari he began producing his own, home-grown luxury grand tourer with its design and production by Frua. By 1968, Monteverdi moved its design and production to Carrozzeria Fissore.

The "375" in the High Speed's nomenclature is derived from the SAE Gross Horsepower Output found in the Chrysler 440
