The Taurus is a success, because it is a dependable, roomy sedan with the standard features buyers are demanding. Reducing the model count makes the buying experience easier.The Taurus faces strong rivals in 1999, particularly from its perennial nemesis, the Honda Accord, which was redesigned last year. Add to that a strong charge from the recently redesigned Toyota Camry. Pricing and performance of the three are basically on a par. So when it gets to crunch time around the kitchen table, the choice in many families may hinge on that controversial Taurus shape.
