To the OP, if you want to get a sense of an all-in price in less than a minute you can try the Discount Car Rental St Martin website, where you can put in your dates and what kind of car you want. We rented from them last time and they were great. Claude met us at the airport and took us to his office in Nettle Bay where we picked up the car, and when we returned it we met them right at the airport which was very convenient.
