I'm up in Manitoba, so these figures are in CAD, but CarCostCanada is a great website that provides you with a PDF showing dealer invoice vs MSRP, the amount of holdback hidden in the price, current factory incentives, all financing options/rates available and even pricing guidance. It really is a fantastic detailed resource to work with when negotiating on a new vehicle. I'm sure there is a US equivalent, Unhaggle for example, but not sure if it is as thorough. This image shows the invoice vs MSRP pricing.
