On my trip to Tallinn I took the chance and bought two models that I couldn't have gotten anywhere in the West...



The 2106 was especially interesting in that it was the modern 1990s version, not sold in the West anymore.

Also available were:
Militsiya VAZ 2104
VAZ 2108 Sputnik
VAZ 2121 Niva
GAZ-13
UAZ 39625 and 31514/Hunter
PAZ 32053 in various variations

I spotted the Volga 21 from the same series at the airport today.

From the 2112 series there was:
GAZ A
GAZ 3110 (looked more like a 31029 with 3110 front and rear)
GAZ 69 with snow plow
PMG-20
Pre-facelift Pobeda taxi.
You can find many of these by googling 'Автомобили на службе'
