Production years: 1956–19?? A 23-seat bus with a carriage-type body on a wooden frame, based on the units of the GAZ-51A truck. The bus was developed in the mid-1950s under the direction of Kaunas Car Repair Plant engineers Paulavičius and Pupeika, based on the GAZ-51A, and went into production in 1956. Four series of the KAG-3 can be distinguished; the first two can be recognised by their three-piece windscreen. As far as is known, more than 12,000 KAG-3s were built, probably including bodies rebuilt during major overhauls. The exact end of production is not known. The following variants were also built on the KAG-3: - KAG-31 multi-purpose van - KAG-32 bread van - KAG-33 special vehicle for road workers - KAG-34 special vehicle for carrying explosives - KAG-317 service bus - mail vans
