It could just be a parts issue. A lot of mechanics will work on pretty much any car, if they have the parts, but if it's not a popular model then they don't want it sitting in their shop for a week while they order parts.

I guess some mechanics will prefer to work with a smaller number of models, because they're much faster if they're familiar with the model, but new models come out every year, and they need to learn how to fix those. If a mechanic can learn to fix the newest VW, they can learn to fix the newest Renault, it just might not be worth their time if they have enough work to do.

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).

So that is circling back to original topic.

I believe person learning GA could learn any other analytics tool. It is just not worth their time.
