Go to Edmunds.com or Kelley Blue Book.

Use information from the window sticker to put all the specifics about the engine, accessories and even the color, into their calculators. When you're done, Edmunds or Kelley will provide you with three prices:

• MSRP. This should be very close to the suggested retail price on the sticker. If it is, then you know youâ??ve put in all of the right information.
• Invoice price. This is the price the dealer paid for the car.
• Average transaction price. Edmunds calls this "What Others Are Paying." Kelley refers to it as "The New Car Blue Book Value." It will usually be somewhere between the retail price and invoice price.
