Terminator is spot on. Don't forget that $42k new is before freight and fees (about $1,500) then taxes on all that (would be $43,500 x .13 in ON = $49,155), rather than the tax on $33k ($37,290 total, plus duty.)
Savings can really add up buying in US, sometimes as much as $10k, especially, as was said, that you buy one with options not avail here.
Importing is lots of paperwork, but not that bad. I've done it twice and will be doing it again. There's also a $225 RIV fee for importing and the joy of dealing with CBSA guards, which unlike the American border agents, aren't nearly as friendly or cooperative.
As for making it road worthy, you probably won't have do a thing if the US version has DRLs.
