This refers to the top picture of the coupe:
In the final years of its life, in the late 1950's, Carrozzeria Monterosa engaged in more top-end creations, probably in an attempt to survive by diversifying production, which had until then focused on middle and lower-end models and on estate cars.
The transition to this category of prestigious and expensive cars began in 1959 with the presentation of an elegant saloon derived from the Fiat OSCA 1500 shown at Turin in 1960, designed by Giovanni Michelotti. The lines were very clean and sporting, with the small peak and steeply-raked front pushing forwards; it was updated in some detail areas for the second series in 1960, and in the same year Monterosa tried some designs on the luxurious Fiat 1800, relying on the talent of Michelotti. The designer, with a lot of imagination, used highly unconventional lines, maybe not the best idea bearing in mind the crisis in the coachbuilding industry.
