How to buy a new car (in Canada)

My parents bought a new car recently (new as in the latest year model from a dealer, not a new "used" car), and as a result I've spent doing the background research. Here are some of what I've learned:

Consumers Reports - Excellent reviews website I use in my research into future purchases that may not have good reviews online. Their car reviews are quite good and more practical minded. A paid subscription required, but I think it's worth the knowledge you gain.

Car Buying Tips - Tips on buying a car; everything from the preliminary research to how to negotiate the best deal. It is mostly US focussed but many of the tips apply to Canada as well and their is a Canadian catered page.

Car Cost Canada - Buy a report on how much the dealer paid for the car from the manufacturer (dealer invoice price). The dealer then marks it up from there and sells it to the public. This report can provide you with a basis for negotiations. The MSRP (manufacturer's suggested retail price) is the maximum price the dealer can charge the consumer and the dealer invoice price is technically the lowest price the dealer can go before losing money on the car (the actual price will usually be 4%-10% higher).

Be informed before you plunk done some serious dough on a depreciating asset!
