Old Chevrolet diesel trucks are found online at sites such as eBay and CarGurus.com, as of 2015. Both sites list diesel trucks for sale, and a buyer is able to narrow search results by year.
When starting a search for an old Chevrolet diesel truck, it is important to keep in mind that the default results cover the entire nation. It is a good idea to narrow down those results by entering a ZIP code and searching a certain radius.
When searching on eBay, a buyer narrows down search results by make, model, year and distance from a certain location. Some of the listings are auctions, but most are sold as a Buy It Now listing, or the seller indicates that he is interested in accepting the best offer. In addition, there are both private sellers and dealerships that sell on eBay, so financing is available on some trucks.
CarGurus.com also lists old diesel trucks for sale, and a potential buyer filters the search results by searching for only Chevrolet trucks. One of the unique features of shopping on CarGurus.com is that a buyer is able to filter results by deal ratings. In other words, the site rates all listings based on market value, which allows buyers to find good deals on truck purchases.
