I'm guessing you mean St. John due to your other question. If so we have had good experience with Conrad Sutton. Added bonus with him, and some others, is you can park in their lot in Cruz Bay. Cruz Bay parking can be a challenge at times. Most St. John companies are the same price in my experience.

If on St. Thomas, Zip rental has been great for us over the last several uses. Including a recent trip to St. John when we took the car over on the barge. Zip is a small local company. They rent more "island" cars compared to the other companies' newer vehicles. We've always found them in good repair and reliable. Also they are great people to work with. They will meet you at the airport upon arrival and leave you with your car and then again for pickup on your departure. VERY convenient.
