As the title suggests, I'm wondering if anyone can give me advice on car rental companies that rent out cars on the Big Island and Maui.

I'm looking for well known reliable companies, with good rates, pick up preferably from Kahului Airport in Maui and Keahole Airport on the Big Island. As I'm coming from overseas, I'm not sure what companies are popular in the US.

I'm particularly looking for a Jeep with removable top.

Thanks
