Bürgerfahrzeug (BAWSAQ: BFA), often shortened to BF, is a German automotive manufacturer in the HD Universe. The player can buy stocks from them on the Bawsaq.com website in GTA V.
Based on the design of most of its vehicles, it is likely based on Volkswagen. Furthermore, Bürgerfahrzeug means civilian's vehicle in German, a parody of how the name Volkswagen roughly translates as people's car. BF has also existed since the 20th century where it apparently did infamous things from 1939 to 1945. Again, this is a reference to Volkswagen, specifically about its involvement in World War 2. BF was once thought to be a division of Vulcar, which is the GTA World counterpart of Volvo but commonly mistaken as a counterpart of Volkswagen.
