This was just something I didn't want to forget...
3. Bypass the salespeople
Edmunds.com, Kelley Blue Book, MSN Autos and Consumer Reports are all great sites to get information, reviews, financing tips and pricing on new cars. But you can use the Web for more than just finding a car. You can use it to buy one as well by pitting local dealers against one another.
Once you decide exactly which car and options you want, here's what to do: Go to a website called Zag and pick one of the sites affiliated with this buying service, such as Consumer Reports, Overstock.com, USAA and American Express. You'll be able to see real prices on real cars from real dealers in your area -- before you provide your contact information. That means you'll be able to pick which dealers you'd like to work with before the bidding process begins.
Once you've decided which dealers you'd like to compete for your business, you simply tell them what you're looking for, then see who comes back with the best price -- no salespeople, no high-pressure tactics, no worries. Once you've gotten the best possible price, go to the dealership and pick up your car.
