|"The 2105 car is a comfortable, high speed five seater
designed for running on any roads except deep rutted earth
roads, at ambient temperatures from -40ºC to +45ºC.
The advanced engine design and the use of high quality oils
provide for sure starting at temperatures down to -25ºC.
If the car is to be operated below -25ºC it should be kept in a warm garage to ensure reliable starting of the engine.
The valve gear driven by a toothed-belt and the improved carburettor with supplementary systems made it possible to provide quiter and more economical engine running and reduced toxicity of exhaust emissions.
The dual-circuit brake system, the pressure regulator in the rear brake circuit, and the automatic adjustment of the brake shoe and pad clearances meet the safety requirements of modern cars,
The soft suspension, modern interior and low engine noise make for pleasurable motoring and restful driving."
