Buying in Germany??
It's easy, you will have to pay a percentage of tax, but the cars are typically better, i.e have been driver on better roads so far. I bought a car for circa 20,000zl from Germany, I think I paid about 1000zl tax.....but it's really a registration fee, i.e new plates etc.
My fully comp insurance with all the bells and whistles was 1400zl or 1200zl per year, don't remember tbh. That's full assistance anywhere in europe, fire and theft, 3rd party etc etc.
Re: Banks,
I'm with PKO, it's a business account so every time I need to call them I'm given an English speaker. re: Internet banking if you do it through Google Chrome then you have an automatic translator installed. However, as we're recently seen, Chrome isn't the most secure, Internet Explorer while by far the worst browser is actually the safest. I think ING and Alior can provide websites in English.....there's 2 previous threads on this here:
