I'm not from Poland but I hope this is hyperbolic. Parts delivery is once or twice a day delivery in most cities in Europe, no matter if it is Renault, VW or a Kawasaki motorcycle. Of course a part can have longer delivery time but not because it is a Renault instead of a Audi. At least not at any reputable delivery business in modern parts of Europe (which I would think Poland is a part of even though I haven't been there since the 90's).
