* Model: A base model coupe will be worth significantly less than a Shelby GT350 or a fastback. Even within models (like the coupe), options and trim packages impact value.
* Condition: This is the biggest factor. A concours-condition, perfectly restored Mustang will be worth tens or even hundreds of thousands of dollars more than a rusty, neglected car. Factors considered include paint, interior, engine, drivetrain, and overall originality.
* Mileage: Lower mileage generally means higher value.
* Modifications: Aftermarket modifications can either increase or decrease value depending on their quality and desirability. Original, unmodified cars are generally more valuable.
* Documentation: Original documentation like the build sheet, owner's manual, and service records significantly increases value.
Therefore, there's no single answer to the question. To get an accurate valuation, you'd need to provide details about the specific 1965 Mustang in question (model, condition, mileage, modifications, etc.). You can then use online resources like:
* Classic car valuation websites: Hagerty, Kelley Blue Book (KBB), NADA Guides all offer valuation tools, though their estimates can vary. These websites often ask for specific details about the car.
* Auction results: Checking recent auction results for similar Mustangs can give you a good idea of market value. Websites like Bring a Trailer show actual selling prices.
In short, a 1965 Mustang could range in value from a few thousand dollars for a very rough project car to well over $100,000 for a highly desirable, meticulously restored example.
