Residents of villages and small towns, where asphalt roads have not yet reached and where “Volgas” and “Moskviches” start skidding after just a few meters past the outskirts in rainy weather or spring mud, have long dreamed of such a vehicle.

OUR FIRST CAR

Boys seem to have a natural pull toward technology — probably something embedded in their genes.
