As a Nomad competitor, it was a successful one, since 15,186 were built in comparison to 7,886 of the competition. The problem was that neither figure was particularly impressive; the Nomad (based on a Chevrolet concept car of 1954) wasn't doing all that well even before competition came over the horizon.
Two-door wagons in general have proven rather hard to sell; those who need the carrying capacity of a station wagon normally carry passengers and want easy access to those rear seats. A low end model like the Ranch Wagon appeals to a market segment who primarily want the vehicle for its hauling capacity but occasionally need to carry people, but a higher-specification car isn't what those buyers need.
A prototype for a 1957 Parklane was built, but instead Ford produced the slightly downmarket Del Rio as their 1957 two-door station wagon, making the Parklane a single-year only model, and quite a rarity.
The Nomad, being based on a concept car, was always better known, but its main reason for fame - its use by surfers needing a vehicle to haul their boards around - came only after both cars were long discontinued. Surfers, although the perfect market for such a vehicle, never tended to buy new.
