* Model: A base model coupe will be worth significantly less than a GT, Shelby GT350, or a convertible. Even within a model, options and features dramatically impact value.
* Condition: This is the biggest factor. A concours-quality, fully restored car will be worth tens or even hundreds of thousands of dollars more than a rusty, neglected project car. Factors include body condition, paint, interior, engine, and mechanicals.
* Mileage: Lower mileage generally commands a higher price.
* Documentation: Original documentation like the title, build sheet, and owner's manual greatly increase value.
* Modifications: Aftermarket modifications can either increase or decrease value depending on their quality and desirability. Original parts are generally preferred.
Therefore, there's no single answer to the question. To get an accurate valuation, you'd need to provide specifics about the car's condition, model, options, and mileage. You can then consult resources like:
* Classic car valuation guides: These publications (like Hagerty, Kelley Blue Book, NADA Guides) provide price ranges based on condition. However, these are just estimates.
* Online classic car marketplaces: Websites like Bring a Trailer, eBay Motors, and Hemmings offer listings of 1966 Mustangs, giving you a sense of current market prices. Look for comparable cars in terms of condition and options.
* Appraisers: For a truly accurate valuation, especially for high-value cars, consult a professional classic car appraiser.
In short, a 1966 Mustang could be worth anywhere from a few thousand dollars (for a very rough project) to well over $100,000 (for a highly desirable, concours-condition example).
