[Biturbos4] 2004 S4; US to Canada

[Darren&Jennifer]

Hi all, I've been lurking here for a few months now picking up a lot of useful information as I try to locate my next car.
I do have a few specific questions about importing a car from the US to Canada, so if anyone has gone through this experience recently (I have previously, just with an older model and not an Audi), I'd appreciate your feedback.

In particular:
1) I'm looking at a 2004 model in New England, has never left the dealer's lot, but was registered as sold last November.  I've heard some stories about manufacturer's not honoring new car warranties when a car crosses the border.  I have spoken with Audi and they are telling me the residual warranty remains in effect.  Has anyone had an experience at a dealership level (good or bad) when doing this?

2) I'm planning on having someone test drive the car for me, since it is so new, I'm not overly worried, but is there anything I should be on the lookout for with this car?

3) As with my current car, I assume the fog lights on the S4 are switch activated?  (I need DRL's once I bring the car into Canada, so would just re-wire them to activite with the ignition).

Thanks,
Darren
