R-SPORT (U) 1955
Danree & Silveira, Montevideo

This was a plastic-bodied sports car powered by a Renault 4CV engine. The engine and the rest of the mechanical components were imported from France and an unknown number of cars were made. Some of these vehicles still survive in Uruguay. They can be considered the first attempt at building and producing in series a genuinely Uruguayan car.

(automatic translation, i.e. not my fault)
First recognized model of authentically Uruguayan design, from the importer of the Solex carburettors, Mr. Danrée (later founder of Dasur) took Renault 4 CV mechanics and even its five-spoke wheels to boost this small roadster (obviously rear engine and traction), with fiberglass bodywork inspired by the first Alpine of Jean Rédele. The model was entirely made in plaster, in order to create the necessary moulds for the bodywork. It should be noted that it was the second car from South America and one of the first worldwide to use new material for the coachwork, glass fibre (the first was the Corvette in 1953 and in Argentina the Institec Justicialista preceded it), material that enlighten automobiles, does not require costly arrays and is easier to work and repair than sheet metal or aluminium .
The car in the puzzles pic was taken at the presentation, that took place in the halls of the Hotel Victoria Plaza, with numerous media such as El País and El Plata.

Yes, supposedly it was Uruguay's first self marketed car, though they took a Renault engine.
