Here is a review that may aid you in reaching your decision:

It is highly recommended to spend the extra money for a convertible rental car. To fully experience The Big Island, it is great having the top down to hear the birds, smell the flowers and feel the warm sun. Sure, it costs more, but is well worth the extra money.
