What do I need to know before buying a new car to get the best deal?

Where can I find this information?

You need to know the retail and invoice pricing of the car and all the options you want. If you know how much the dealer paid for the car, you can determine how much to offer for the car. Use edmunds.com or kbb.com for all the research.
You also should compare car insurance quotes for cars before buying one, for example here - carinsurance.yoll.net
http://urlhawk.com/csf - here's a good website to look for real good, affordable and quality vehicles from official government auctions! I bought my Honda Accord for just $2250 with a milage of 5,270! And it's been already a year I'm riding my car and it's still doing well! I've recommended it to my friends and all of them are enjoying their used cars and have no problem with it! One of my friend was lucky! He got a tuned Ford Mustang for just $970! ADDED: I just found out that it's been featured in Auto magazine and they received good editorial reviews!
