There are multiple pricing sources available on the internet - autos.msn.com; autotrader.com; car.scom; motortrend.com; edmunds.com to name a few. The simplest and most accurate site I've used to get a price that I should be paying is Edmunds.com. They have a link near the top of the screen on the opening page called "true market value," or TMV. From this link, you can configure your car the way you want to buy it. You'll see 3 prices - invoice, or cost to the dealer, the MSRP, and the true market value price, or what others are paying. This is a reasonable guide to what you can expect to pay. For example, I recently purchased a new LS460 with comfort package and navigation. The MSRP was $69,200. The TMV price was $65,200. I paid $64,500, so it's right in the ballpark.
With all the information available today, I'd hate to walk into a dealership and not have as much as information as possible. Good luck!
