Law / Changing car registration from Foreign to Polish [6]

I have bought a car in France, and arranged export registration papers and temporary insurance to transport it to Poland.

Once in Poland, however, I do not know where to begin in order to getting the car transfered over to polish registration. I have residence papers and pesel number in Poland.

Any ideas on the process and sequence of events would be appreciated

Also costs.

Also to mention, the car is 15 Years old, with one previous owner. Buying privately not from a dealer.
