Mazda turned to its partner Ford when it need and SUV in a hurry. Ford's already popular Explorer provided a good base for it. Ford Explorer mechanic parts are often the same as Mazda Navajo parts, though many trim parts are different. Some outer trim like the grille and tail lights are different to maintain at least some individual identity. The Mazda Navajo was only offered as a two door to avoid competition with Mazda's own four-door MPV. The lack of a four door was probably a big reason that the truck was discontinued after poor sales. The Navajo was not replaced until the Mazda Tribute came out about a decade later. Mazda no longer has a traditional SUV on offer and sells the CX5 and CX9 crossover model to cover that market.
