Previa minivans went on sale in 1990 as a replacement for the Toyota Van. Previa had either rear-wheel drive or permanently engaged 4-wheel drive (All-Tracs) and were offered in either Deluxe or LE trim. The only engine was a 2.4-liter twin-cam 4-cylinder rated at 138 horsepower. A 5-speed manual transmission was standard; a 4-speed automatic optional. The Previa’s engine was mounted below the front seats, but tilted to one side in order to provide a flat floor. It’s accessible through a panel in the floor or from underneath the vehicle. Fluid reservoirs and other vehicle service points can be reached by opening the hood. Four-wheel disc brakes were standard on LE models and an antilock system was optional. A sliding right-side door and a one-piece liftgate augmented the front doors.
