I wonder how much of this is intentional, and how much of it is simply cultural.
By that I mean... I know that some countries do not put much stock at all in 'being on time' so they may feel that they were still within an acceptable tollerance of being on time for their delivery.
Example, I have a few friends who have lived in China, and I have heard multiple times that if you tell someone to meet you at 4PM they might show up anywhere from 3pm until 6pm. So with that much of a gap when it is a small thing, I could understand some thinking on such a huge deal that a larger gap might be expected.
Still... I do hope they come here. I would really like to see them, crawl around in them, and if others report well then I would buy one of the four door diesels.
