Bringing a car from Germany to Poland + Registration

Hi everybody!
I'm from Austria, my girlfriend (actualy finacee, but the word sounds stupid ;-)) is from Warsaw and I intend on buying a car in Germany and registering it on her name.

So, I want to buy a Volvo S60 with a 1.953 liters engine.
As far as I heard, that should cost me 3% border-tax/customs when I import it. Right?
Then my question is, can I buy the car on my name in GER and then have my girlfriend register it in Poland on her name? or must she be the owner to register it?

What other costs, taxes etc can I expect?

greetings from Austria,
Christian

happy speculating.

viva capitalism

She is moving to Austria in July but until then she doesnt have the nerves to drive across half of europe only to sign a contract at the car dealer...
Come to think of it, I could mail her the contract... hmm...

So anyhow, about the fees... Anybody know the procedure?
-customs
-translation of the cars documents
-registration
-etc
