I have info from a good source on the discount.
Now regarding the price (which seriously who cares)... but anywho.
This is how I did my math, I washed off the PDI/Freight and exchange which is pretty much nil.
US price is $38,995 + 6% = 41,334
CAN price $44,995 = 44,995
-----------
Difference = $3660
That's $3500 ISH.
Yes PDI is more here, so the difference creeps up to $4000, but don't forget there will always be other small costs to incure. So I rounded off.

Gotta love critics, don't mention the US price and they go ballistic, mention it and they go ballistic.
Thanks Zombie for those more detailed numbers, which even if you remove the $4000 discount shows the difference to be around..... $4000.

If you live on a border town, great if not think about flight/gas to get to US to pick it up, or shipping etc.
Might as well buy this one in Canada IMO. Unless you don't want NAVI!
