I've read that the car prices are fixed to prevent sticker shock. Cars in Canada are cheaper than in the US if you do the exchange rate even though they're the same car. Special restrictions are now in place because people used to drive over there, but a car, and drive back. Now it's a lot harder. I think they do that here too. I've seen reviews of cars only available in the UK and they'll estimate the price to be "$30,000" based on the exchange rate, but then the car will come here it'll be $25,000. I think they do it to prevent sticker shock.
