You can find better pricing if you buy from a private seller, but the vehicle is going to be sold as-is, and the seller is not required to do a vehicle inspection or provide a vehicle history report. A dealer will have a standardized inspection process, they'll provide a vehicle history report, and if you notice anything wrong with the car, you can ask the dealer to fix it. There's also a recourse process if a major issue isn't disclosed. However, there will be less room to negotiate your price.
