Yes, unfortunately very few cars are still on the road, in Russia about 5 as far as know, also about 2-3 in Belarus and Estonia. The weather conditions are not quite good? especially in Saint-Petesburg, that's why I only have a ride in summer. In winter our salty road will kill it.
Up to this time I think we dont have problems with spare parts, may be only with body and some specific parts...Some rare parts I have bought in Poland, but still they are possible to find in Russia like LCD dashboard,front and rear original electrical window lifts and some others. For example, I have a spare front Irmscher bumper, also saw some Irmscher kits on sale.
