You can find older-model Cadillac cars for sale by searching on classic car classifieds sites such as ClassicCars.com, Hemmings.com and OldRide.com. Auction sites such as eBay.com and general classifieds sites such as Craigslist.org also commonly contain listings for various types of old Cadillac cars.
Listings on ClassicCars.com for older-model Cadillacs contain pictures of the car along with a description of the car's condition and features written by the seller. In many cases, cars listed on the site have been restored to resemble their original state, though some are sold simply as is. Users interested in purchasing a car listed on the site are able to contact the seller directly through the site, using a built-in messaging system. Though the site leaves the payment aspect of the sale up to the involved parties, it does offer tools to allow buyers to arrange shipping methods if they are unable to retrieve the Cadillac in person.
Alternatively, eBay.com facilitates all payments made for items sold on the site but does not offer any help arranging shipping methods. Some sellers offer shipping options, such as standard freight shipping or driver delivery, included with the purchasing price of the car. In these instances the shipping methods and costs are displayed in the car's listing.
