@Nikola: I went to service at Zemun dealership .. all in all their garage looked more serious than of those
criminals "Djordjevic"
Regarding inspection and changing of parts .. yep, like I said almost nothing was ever looked or checked as it was supposed to be according to the list in the guarantee book.
To be even more ridiculous, they charged me 14EUR for changing of 4 light bulbs which I brought to them as they don't sell them. Also, they charged me for some other small stupid things .. like diluted water (for mixture with antifreeze)

.. crazy people ..
