Ros surpassed in sales even "Greek classics" like Alta and Styl Kar, and the characteristic shape of its trucks could be seen for several years in every corner of the country.
The Alfa-Ros brand was introduced in 1966 when S. Konstantinides cooperated with A. Apostolopoulos, designing and producing 'proper' (unrelated to motorcycles) three-wheeler trucks.
In 1968 A. Apostolopoulos made his own company (producing the Apollon truck, similar in appearance and almost as reliable) and thus S. Konstantinides continued with a new brand, Ros.
A relative of the company founder, Ilias Konstantinides also made his own Ilion brand producing Ros designs.
Ros terminated production in 1976 when the type could no longer suit the needs of Greek professionals and competition from imported trucks became stiffer.
