My '10 328i X-drive and my wife's '96 Z3 1.8 (Euro spec) were just passed over to the shipping company to send back to Canada.
We have been in Europe since '07 and are heading back for good now...
Bought the Z3 in '08, and have put about 25K Kms on her since then... lots of autobahn. Did a nice 2-day drive down to Port Grimaud on the French Riviera (almost got thrown out of the country of Monaco) and burnt ourselves pretty bad on the sunny hot drive down.
Bought the 328i (Canadian Spec) new in Jan '10, and got 32000 Kms on her, mostly autobahn as well, although this one is my daily drive.
Now they are sitting at the shippers yard, waiting to get loaded onto the truck, to get loaded on the boat, for the sail to Halifax, before being shipped cross country... We hope to see the 328i in late May, but the Z3 will show up a month later due to the 15 y.o. rules for importation into Canada, we didn't want her arriving before Jun 1st, therefore she will arrive in Edmonton approx 25 Jun.
God Speed to my girls, may your sailing go good, and you arrive in one piece.
