Auto parts store "razdolye", an excellent store, a large assortment of auto parts for Soviet cars and foreign cars, reasonable prices, I often apply, mostly for all spare parts the most reasonable prices are in this store (I had to compare often) , experienced sellers who know the range work, do not make bad discounts.
In principle, everything you need for a car, or rather basic necessities, can be found, if something specific and of course depends on the brand of the car, then you are unlikely to find anything.
