They load up in Yokohama, there are west coast ports in Vancouver WA, Richmond CA, then through the Panama Canal, east coast ports in Jacksonville and Baltimore I believe. You can find this stuff using marinetraffic.com or something similar.
But as far as I can tell there is no way to KNOW which boat your car is on. Rarely it seems people have been able to get this info from the dealer, but that doesn't seem to be the norm.
But, as someone who's played this game already, just sit back and relax and wait for your car to show up.
