It depends on the model, options and overall condition of the drivetrain, interior and exterior. Is it an LS or an LT? If it's an LT does it have the 1LT, 2LT or 3LT package? Are there service records for it? Any dents or paint issues? Has it been in an accident? Is the interior clean and not worn, torn or frayed anywhere?
There's a lot that determines what a vehicle is worth. If you supply that info, it would be easier to determine if it's a good deal. And it would be a huge benefit to you, too, to know all these things about a car you're interested in.
