Law / Buying and registering a car as a non-resident Polish citizen [4]

So i live in the USA and i come to europe about 5-6 months each year; i'm tired of blowing loads of money crappy rental cars. I also have a situation where I must be careful not to establish tax residency outside of puerto rico due to some special tax program I'm a part of.

Is there some way that I can buy and register a can in Poland? I'm not really into using the address of my cousins as last time I did that I got bi+ched out about some crazy idea that the sheriff could show up looking for me. lol

SO I don't really have an address in Poland (I can get a mailing facility address) and don't care to have one. I don't really plan to be in PL for more than 30-60 days in any year, mostly I will use the car in other parts of the EU and garage it in Poland during the winter when I'm sitting on a sunny beach here sipping cold beers.

Does anyone know a lawyer that can take care of this for me? Register the car, receive my mail, take care of the insurance. I'm happy to pay well...

If there are better solutions like company in Estonia or Bulgaria or whatever please suggest, I'm open minded to solutions around the bureaucratic red tape...

Cheers!
