This model is a copy of a real car called GAZ-24TS, namely an old Volga 24 station wagon in taxi version. You can watch a video of this car below.
There are 2 versions of the model in the archive, an exact copy of the real GAZ 24TS (24ts), and not an exact copy (24TS-TAXI), with a "TAXI" sign on the roof and the ability to "taxi" in the game.
Words from the owner of the car, Lev Belyaev: “The GAZ-24TS is the rarest, oldest surviving example of the family of “twenty-four station wagons” from 1971 to 1992. This particular car is the earliest of the known by chassis number 001174. She has miraculously survived to this day, thanks in part to me."
