Why are Boxsters more expensive in Canada?

I bought my boxster in the states, new york city, manhatten. I live in Canada, i saved about $5000.00. It has nothing to do with the currency, although it does favour us now to buy from the US, because you have not changed prices accordingly(if this makes sense).

But, when i worked at BMW, we would sell used BMW's to the customers all over the US. At that time the American dollar was strong and the US customers were saving about $5000, on $50,000 car purchases. It is a grey market, you really are not aloud to export/import cars. I know for a fact that BMW Canada will not let an owner sell the car within the first year to the states. So you have to wait until the car is one year old before selling it in the states. Our dealership had been fined because a customer sold his BMW in the states. We also had a big problem with the russian mob buying X5 trucks, and shipping them to russia, and turning them over for double the price. Our dealership would get fined by BMW Canada, although it wasnt our fault that they would ship them, we didn't have any control.

Aparrently under the nafta aggreement, import/export of cars, America pays lower taxes and tariffs. N Canadians don't have an aggreement, and we pay higher prices for cars. so for some reason canadians don't have an agreement with germany/europe under the nafta agreement, when it comes to automobiles, which i don't understant, and am looking into. if anyone knows exactly the deal, inform us, or i am looking into it, and trying to find more information in regards to this ordeal.

our local toronto star, has posted many articles about cross boarder car shopping, they usually compare the porsche 911 for some reason to show the savings. i don't think that i'll ever buy another car here in canada, it just doesnt make sense.
