Don't go through the dealer sites. Use something like TrueCar.com or Edmunds which will give you online quotes from multiple dealers. Also, I would recommend NOT using your real name, phone number, or your regular email address. Do not give the dealers any information about how eager you are to buy, how soon, or what kind of financing you may want. Basically, you want to give yourself as much information as possible, and the dealers as little as possible.Also, these online/email quotes, do I actually email the dealer, or go to their website and do the "Request a Quote" deal?
