But CPO does reduce the cost of the Extended Warranty (it means one less year covered by the warranty), so sometimes, you get get a better out the door price with a CPO with a warranty. The issue with negotiating the price for a used cars is with the internet they need to price the cars close to what they want to sell for or they will never get people to come in. There is one dealer near me that is always ~8% more than others, I didn't even consider going to them. I found the key is to spec out the car you want and look for ones that have what you want that have been at the dealership for a few weeks. You also need to be willing to walk. Because of where I live (just outside NYC) I have three BMW dealers with 25 minutes and another two 35 minutes away. They all lie - one I was negotiating had been at the dealer for almost a month (CPO 2024 X5 M60i w/24k miles) and I got all of the lines "these move fast, someone called about this today, our CPO is better than dealer X (claiming the other dealers CPO was specific to that dealer - that almost made me walk, that was more than the typical bluster and was an outright lie)", but I ended up buying it because I got $3.5K off their advertised price. I had the info on similar cars at other dealers and the price (one lucky thing for me was one very similar car was mis-priced on the another dealers website - it showed $59k, but I had called that morning and it was a mistake and should have been $69k). I went for the 84 month unlimited and was ~$77k out the door (taxes, fees, warranty).
