Full-size mock-up of the Moskvich-2141 mod. 3-5-6, side-front view

A distinctive feature of the 3-5-6 model was its recessed front end with massive horizontal ribs on the radiator grille and protective screens placed over the standard round headlights. The front marker light was divided into two sections by a vertical line, rather than a horizontal one as on the 3-5-5.
