>Cars in Canada are cheaper than in the US if you do the exchange rate even though they're the same car.

Eh? Since when? I live up here, and cars have almost always been cheaper south of the border. Maybe not now that our currency isn't as bad as it has been in the past, but.. Also, cars up here tend to be less well equipped with extras than those in the USA, so they damn well should be less expensive than they actually are in practice.

It used to be very common practice to buy in the USA and drive it north.
