There are generally three sources of used cars:

  PROS CONS
New Car Dealer They want repeat business so they will likely treat you well. They can often offer some type of warranty. They are usually the highest price.
Used Car Dealer Good used car dealers usually check out the car to make sure it is in good shape. They may offer a warranty. Not all used car dealers are good. Prices are usually lower than a new car dealer but not as low as a private owner.
Private Owner Usually the lowest price. No warranty is offered and you take the car as is.
