Couple of notes, there are certain cars you cannot bring over to Canada no matter what.
Dealerships farther away from the border are more likely to deal with you.
Relatively inexpensive to bring over border >750 normally.
Must have cash.
On a side note, my parents recently purchaed a Lexus RXH Hybrid SUV from the US. Last years model, lease back return - paid total of 37K US including taxes, fees etc.
Starting price for base model in Canada is 62.5K - if they were to buy new in the US, would have been about 44 - still almost 20K less in the US.
If you have the cash to buy the car, its more than worth it at the exchange rate. The only problems my parents had were getting one way tickets, US customs gave them quite the hassle.
