Things You'll Need
Instructions
Check out auction sites like ebay as well as specialized antique car-selling sites like Auto Trader Classics or NADA Guides (see "Resources" below). Check what buyers are paying for cars that are in similar condition to yours. If you see a car that, based on the photo or description, is practically identical to your car, email the seller with questions to firm up the similarities. Be sure to compare key indicators like mileage, body, interior and mechanicals.
The Auto Trader Classics and NADA Guides websites both have plenty of listings where you can find a qualified classic car appraiser. Email the appraiser a photo and description of your vehicle, providing as much detailed information as you can. If he's in the area, a personal showing is a great idea.
Check the Yellow Pages to see if there's a local classics car dealer nearby. Take your car in and ask him for an appraisal.
Many cities host classic car shows. Bring your car along to one and you'll find plenty of experts willing to give you quickie appraisals or value ranges. You might even find a seller.
