* Condition: A concours-quality, completely restored example will be worth significantly more than a car needing restoration or with significant rust. The condition of the paint, interior, engine, and chassis all heavily impact value.
* Mileage: Lower mileage generally commands a higher price.
* Options: Rare or desirable options (e.g., specific engines, transmissions, interior packages) increase value.
* Modifications: Modifications, while possibly improving the car in the owner's eyes, can *decrease* its value to collectors. Original, unrestored examples are generally more valuable.
* Location: Market demand varies geographically.
Therefore, there's no single answer to "how much is a 1966 Chevrolet Caprice coupe?"
To get a price estimate, you should consult resources like:
* Classic car valuation websites: Hagerty, ClassicCars.com, NADA Guides offer valuation tools that consider the factors mentioned above. You'll need to input specifics about the car's condition and options.
* Online classifieds: Check sites like eBay Motors, Craigslist, and Hemmings to see what similar cars are selling for. This gives you a sense of the current market.
Expect the price to range from a few thousand dollars for a project car needing significant work, to tens of thousands of dollars for a highly desirable, well-preserved example.
