At this point, we'd determined the unimpressive Chevrolet Impala was overdue for a redesign. Its short list of good points included simple radio controls and a large trunk. Although a large sedan, the cabin is less roomy and comfortable than many smaller offerings. Handling is clumsy and powertrain refinement falls short. The rear seat is skimpy for a car this size and the car's fit and finish are second-rate.
