Buying a 2012 Ram 1500, and saving $10000 off of MSRP.
I pulled a truck from the dealers web inventory then went to the Car Cost sight put in all the options to give me the dealer cost. I then went to the dealer,ask them to pull the truck. I asked them to give me their best deal all in price(truck,tire tax,gst and administration fees)so I had no surprises when paying for the truck. They came up with an offer I countered with 3% over cost and they accepted ($1,200.00 less then their best deal). The whole process in the dealership took 45 minutes. They had the truck cleaned and full of gas the next day as promised. If you can go into the dealer with two or three of their cars already pulled and priced, let the sales person know what you are planning to do(or phone ahead to see if they are open to to price over cost) and don't waste their time I believe they are more likely to make the quick sale at a good price. I purchase about 1 car/truck a year and always use car cost and call the dealership that has the car with the options I want to insure they will deal cost plus. This has saved me huge amounts of time and aggravation and if the sales person does not live up to their promise of cost plus no hidden addition charges get up and leave.
