Hawaii full size car rentals can be a Ford Fusion, Chevrolet Malibu, Nissan Altima or Mazda 6. The benefit of a full size car is a bit more space than a mid-size or standard size, but it costs a bit more. However, it is a comfortable size for space. For families with tall passengers, 4 or 5 passengers, car seats or needing legroom this is a great choice. Sometimes size matters to accommodate passenger comfort.
