Ford might have been angling to poach buyers who were considering Chevrolet’s Nomad wagon, but it didn’t work out that way. According to the report in Wikipedia, “The impetus for the creation of the Del Rio was Ford’s desire to remain in the two-door sport wagon market started by the Chevrolet Nomad and Pontiac Safari.
“While the Nomad was Chevrolet’s most expensive model, offering a premium vehicle with a show-car-inspired body style, the Del Rio was strictly based on an existing product, the utilitarian two-door Ranch Wagon, Ford’s least expensive station wagon, as part of the Custom 300 series.
“Beginning with the basic body, buyers of the Del Rio were offered a unique two-tone paint scheme (optional), better quality interior and exterior brightwork (including gold anodized aluminum accents) and a higher grade vinyl upholstery. Four-way power seats were available.
“While the Ford sold more Del Rios in 1957 (46,105) than Chevrolet did with its Nomad in its three years of production, Ford terminated the Del Rio program at the end of the 1958 model year after selling only 12,687 of its “sport wagons.”
