Yes, Hyundai Canada is completely seperated from Hyundai USA.
I should mention, the true "Sleep Mode" doesn't really happen till January, it sometimes happens in December, but it really depends on Hyundai's numbers. If they look like they are within striking distance of their goal from HMC, they will release the flood gates and they will offer the moon in terms of incentives.
If the already hit the goal, they cut back on the incentive money, and try and improve the bottom line for HMA for the end of the year.
If I had to say when the best deals are, I would have to say the summer months...
