Your dealer should be able to give you the VIN number for your car and the name of the vessel on which it is loaded. It seems to take about 10 days to get to the east coast from Germany. Here is something that poster "Leong" said on April 19, 2005 about tracking your car:
"If you have your VIN, you can go to
www.wlna.com, go to cargo tracking, and find your car if its being carried by this line. Wallenius Wilhelmsen carries some cars to the East Coast USA, then thru to NZ, AUST and SE Asia."
This didn't work for me since my car was delivered to San Diego. In my case I was able to figure out the ship even before the dealer gave me the name through some detective work. I knew that Porsche uses VWT (Volkswagen Transport) to move their cars to the west coast. I then looked for ships departing Germany (Emden) about the time I expected mine to leave. I tracked down a VWT ship that was destined to San Diego and sure enough it turned out to be my ship.
Unfortunately I could not find out a way to track the movement of the ship so I just had to depend on the ETA info supplied by the Port of San Diego website. I guessed my car arrival correctly within 1 day. I actually got it one day sooner than I had expected. Mine was off the ship, through PDI and to my dealer within three days of the ship offloading. One edge I had, my dealer is 90 miles from the Port.
