At $245 per day they won't go flying out the lot. (And 70Boss says those rates are negotiable anyway) They are the wrong car in the wrong place in the Hawaiian Islands. There aren't many places you can get to sustained speeds over 50 mph there.
The hot ride to rent would be a Mustang convert. or a Jeep CJ.
I was there a long time ago and you could rent a Lincoln Town car for the same price as a Mustang convertible, but the convertible was what you wanted!
