One nice bit of caution should be mentioned here. Many insurance companies do not cover "exotic, prestige, off-road etc) in case of an unfortunate circumstance. It is strongly suggested you check with your insurance carrier, credit card company or purchase the unbelievably expensive add-on insurance.

Exotic cars and motorcycles etc are easy to rent in Hawaii for mega-$$$$. They also were in many LAX car rental stables a few years ago.
