* Model: Is it a coupe, fastback, convertible? Different body styles have vastly different values.
* Condition: This is the biggest factor. Is it a pristine, concours-ready show car, a driver-quality car with some imperfections, or a project car needing significant restoration? The condition dramatically affects the price.
* Options: Factory options like air conditioning, power steering, specific engines (like the 289 HiPo or K-code), and transmissions significantly influence value.
* Mileage: Lower mileage generally commands a higher price.
* Documentation: Original documentation, like the owner's manual and build sheet, increases value.
* Modifications: Aftermarket modifications can either increase or decrease value, depending on their quality and desirability.
To get an estimate, you should check resources like:
* Kelley Blue Book (KBB): This is a widely used valuation guide.
* NADA Guides: Another popular valuation resource.
* Hagerty: Specializes in classic car valuations.
