This really depends on the mileage and features of the car. Good price ranges for a 2002 Pontiac Sunfire range from $2,000 to $3,500, depending on how many new parts it may have.
A good price for a Pontiac Sunfire would be between $1,500 to $2,500 depending on condition and mileage. If the car was well taken care of and has been maintained, it would be worth this price.
I would like to recommend you to sell it for USD 5,000..Still in good condition? What about the tires and others? Are all of them alright? If yes..Then I think you could be able to sell it for USD 6k maybe.
