/ I'm moving to poland; I got sick of the London lifestyle. Find work?
Finding work is a tough one if you don't speak Polish. The usual English teaching, try Berlitz or any Callan school as they give all the training needed and want native speakers.
Hard to help without knowing where you are going and what you can do. If you buy a car in Poland it will need to be registered in your Polish girlfriend's name, we can't easily register a car there without being oficially 'meldowany' (maybe spelt wrong).
If you take the Uk car there you can drive it no problem but expect problems getting pulled over for no real reason. You can't register a RHD car in Poland, getting it converted in possible but expensive depending on the car.
Poland is a great place to live I was there for 13 years, It is more expensive now but you can still buy land and build a house. You can still call an ethnic minority a black person, without being called racist.
UK has gone mad, keep an open mind, avoid the expats and Poland is a wonderful place to live.
