Car Import from US to canada and vice versa . . . .

[sarimraza]

Dear

I have heard there is disparity in prices of vehicles between US and canada, but there are certain complications such as currency, duties, and warranty limits . . .

Has anyone been in this business and has some know how as to which car (make and year) would it be possible to trade between US and Canada (either way) and manage to make a profit ?

Thanks
