95 octane! On the cars that typically travel around St. Maarten that would be a huge waste of performance and cost. Luxury autos that require premium fuel will run just fine on 89 or 90 octane gas, especially in St. Maarten. There's no autobahn there where you'll need gas that rich. Personally, I would not bring a luxury auto to St. Maarten for a variety of reasons but would opt for a smaller SUV-type vehicle where you would sit up a little higher, have good visibility, and not have a trunk that you'd have to worry about being broken into. Something like a Toyota RAV4 or Subaru Forester would be a great vehicle to have here and require non-premium 87 octane gas.
