For its first SUV, Mazda turned to Ford, which was a natural choice, since the two automakers have been linked for more than 25 years. The Mazda Navajo was a thinly disguised Ford Explorer, with a few minor changes to the exterior, such as a new grille and taillights. The Navajo was available in only one version -- a two-door model with a 155-horsepower, 4.0-liter V6 engine. A five-speed manual transmission was standard, while a four-speed automatic was optional. Standard features for the Navajo included a part-time four-wheel drive system developed by Ford and rear-wheel anti-lock brakes that operated only when the vehicle was in two-wheel-drive mode. Other standard features included tweed cloth seats, power brakes, power steering, power door locks, power exterior mirrors, 15-inch wheels, and an AM/FM stereo system. Options included a sunroof, air conditioning, leather seats, and a cassette player. The Mazda Navajo was a reliable, fun-to-drive vehicle, with a comfortable interior and good acceleration, according to drivers. Many of the vehicles now have high mileage, but for the most part drivers reported having only routine maintenance problems with the vehicles. However, a few drivers have reported that their vehicles needed frequent repairs, and that parts could be difficult to locate.
