Estonia- 25 was the first TARK vehicle with a monocoque and pus- rod suspension. It also included gas- filled shock absorbers for the first time. The Kamov Helicopter Plant built vehicle monocoques. The project began in 1987, with the first vehicles racing in 1990. The cars competed in races for the F- 1600 and Scandinavian F- 4 classes. The gearbox was, as expected, based on the ZAZ- 968. The car was powered by engines from the Lada 2106, 2108, and VW Golf GTI models.

The automobile was very expensive, thus in 1991, a tubular frame version of the Estonia- 25.20 was built, which cost almost half as much. The fall of the USSR put the TARK (Kavor) in a terrible condition. As the USSR Championship ceased to exist, the need for racing equipment decreased. A total of 66 automobiles were built, 18 of which were monocoques. Cars were used in Soviet, Russian, Ukrainian, Baltic, and Scandinavian competitions. They are now utilized in retro races in Eastern Europe (HAIGO), Russia (MCGP), and the Baltic.
