I was in Yerevan for several days, just before the trip to the service station, I discovered that an oil glass was leaking, I went on purpose, taking the opportunity to buy 2 rubber gaskets, everything turned out to be in stock, the price was about 13,500 rubles, the manager happily showed what was available, and even more joyfully announced to me that without an Armenian passport it was impossible he would sell it, I had nowhere to take it, the Mercedes center in Yerevan is not the most visited institution, no one carries a passport with them for nothing, I bought a replica at the market for 1,700 rubles. I can't check out the repairs, they used to do everything well in Mercedes centers in Russia (my experience is Moscow and Smolensk).
