Seating

The Rio can accommodate five passengers, but reviewers recommend that you limit it to four since the rear seat can be a squeeze for adults. The front seats may also be a tight fit for taller adults, who will have a difficult time finding a comfortable driving position -- especially with limited seat adjustments and no telescopic steering wheel.
