So, to your door price, that would be $54,000 + tax ($5400) + RIV fee ($300) + A/C tax (100) + Provincial Inspection ($300) + your time if you brought it up yourself.
So to find a similar car in Canada, you'd be comparable at roughly $60,000. Then again, there is tax if you bought it at a dealership (or half the tax in SK) and a provincial inspection if purchased out of province. $57,000.
Gerbie had or has an '07 like the one you described with 17K on it for $54,000 which is within spitting distance.
I'm not saying there are not sweet deals in the States...that's where I bought my car. I'm just saying if both cars were the same price or close enough, I would buy the Canadian one....but then again, I'm sure so would everyone else.
