Hi Gurps,
If the Bellingham dealer is hungry enough to help you out, he may allow you to use his home address to register the car and put washington license and insurance on it. No need to wait the six months. Drive it home the same day!
Of course he would honour the warranty, they have to. Any dealer in the US will honour the warranty, just not Canada, unless you register it to a US address with valid state plates or wait until six months after the "in service" date.
The "In Service" date is a tricky one. Depending on who you talk to at Nissan, it is the date in which the car was registered with the State department of Motor vehicles OR the date it was sold and taken off the lot.
I bought mine with 3800miles on it and there was some concern over the "in service" date. The two were a couple weeks apart. Finally called Nissan USA with the VIN to find out what the date was, and picked up the car 6 months + 1 day later.
Someone posted the letter I received from Nissan regarding the warranty (I think on page 2 of this post.... I'm glad to see the forums are a good source of info). Print it out and use it as your guide for the warranty. Show it to your dealer in Bellingham, maybe he'll help.
Personally, I would want the warranty valid in Canada, haven't needed it yet, but if something major goes wrong, it would certainly be a hassle having it transported across the border for service.
Now the irony of all this, is I'll be moving to the US in the next month and will have to import my car back to the US... go figure
Let me know if you need any more help.
