Over the years the Chevrolet Step Van has had many uses from delivering bread to milk to packages to auto parts. This retired van was found in eastern North Carolina. It's hard to determine the year because there's been little styling changes over the years, but we think this van was probably built sometime between 1968 and and the mid '80s.

This 1956 Packard Clipper found in Texas was one of the last Packards built in Detroit.

The Clipper was built in 1941-1942, 1946-1947 and 1953-1957 as an entry-level vehicle. In 1956 the Clipper was classified as a stand-alone marque. (Photo by Peter Hubbard)

This early second-generation Ford Ranchero pickup (1960-1965) was found living in retirement in Utah. The second-generation Ranchero was based on the newly introduced compact Falcon sedan. Ford believed the market wanted a more practical vehicle, one much smaller, lighter, and cheaper than a full-sized pickup truck, and indeed the Ranchero sold well. The standard engine was a 2.4-liter straight six with a 3-speed manual or a 3-speed Cruise-O-Matic automatic. (Photo by Jim Prueter)

Chevelle became very popular in the mid-to-late '60s and Chevrolet billed it as "America's most popular mid-size car." (Photo by Nick Nunkovich)
