Interesting. That would suggest you have just been allocated a car from one of the later boats.add to that, i've just noticed the final invoice says the delivery date is 30 september
Probably the Glovis Sunlight which has just left California arriving Zeebrugge around 12/13 Sep. Or the Glovis Courage, which is unlikely because it is next to load in San Francisco, should arrive at Zeebrugge around 20 Sep.
