mt is right. Chasing the invoice price, today, is not useful information. In the late 90's the dealers got fed up with customers demanding to see invoice and expecting to pay back of invoice. The manufacture and dealers began moving the invoice price closer to MRSP. Some vehicles today have a inv to MRSP spread of 6%, others 2-3%. A more accurate way to determine the fair value price. Is MRSP versus sale price (not including T&L) If the MRSP is $55k and the buyer has negotiated a sale price of $45, then the buyer is getting a 19% discount off of retail. Subject to vehicle type, options, demand, location and time of year,,some people get 25% off and others 5%. Another helpful tool can be to research what others have paid for the same vehicle. Dosn't mean you will get the same price or will pay as much. But knowing the average is helpful in determining what you will offer. My neighbor just bought a $65k MRSP truck for $45.5K. 30% off sticker. The sad part of that deal,,,its a FORD.
