That's a bizarre price discrepancy. I wonder if there's some credits in there that I'm not getting in Canada, or that aren't included in the initial price tag.
Those prices are without any incentives, actually. If they actually manage to get the 'made in America' requirement for the batteries, then I believe they'd be eligible for an additional $7500 off that price. Depending on where you live, there may be still state incentives available right now too.
