Law / Costs for importing a car from Germany to Poland. [34]

I hope I can help you...Try to find the city council web site in poznan, because you can register on-line. Than they will give you a ticket for a especific day and time for you to resgister the car, so you avoid queuing.

I know that the system is working in Gdansk so I just assume that in Poznan is smiliar.
take care and don't give up.
