* Condition: A completely restored, concours-quality car will command a significantly higher price than a project car that needs extensive work. Everything from the paint and interior to the engine and mechanicals impacts value.
* Options: The original options when the car was built (engine size, power steering, air conditioning, etc.) greatly influence the value. A rare or desirable option package increases the price.
* Mileage: Lower mileage generally means a higher price, all else being equal.
* Location: Prices can vary geographically due to market demand and collector density.
* Modifications: Aftermarket modifications can either increase or decrease the value, depending on their quality and desirability to buyers.
To get an idea of pricing, you should check online resources like:
* Classic car auction sites: Sites like Bring a Trailer, Hemmings, and eBay Motors often feature 1968 Impala convertibles for sale. These listings will give you a sense of current market values based on the condition and options of specific vehicles.
* Online classifieds: Websites specializing in classic cars will also have listings.
* Local car shows and clubs: Attending these events can give you a feel for the market and potential prices in your area.
Without knowing the specific condition and options of a particular 1968 Impala convertible, it's impossible to give you a precise price. Expect to see prices ranging from tens of thousands of dollars for project cars to well over $100,000 for meticulously restored examples.
