can i buy new GTC from US if I'm canadian
 

Hey guys, I am looking to buy a new gtc from US, it is about 50k cheaper than buy it from canada, is it a wise decision? please let me know, thanks !

I don't see why not, once you factor in the duty you're still way ahead. Warranty will still be valid in Canada and you won't need to change the cluster or anything since it has the km markings on the speedo.

Yes you can, you'll have to pay gst and duty and the gas guzzler tax, so look into it really closely.
The dealer can activate the day time running lights easily as well for you.
I think the dealers near Chicago know all the ins and outs by now, but maybe a broker is a good thing as well.
This guys is cool and helped my friends over here in Edmonton.
