Sure, you can head out and explore St. Martins without a car. But with so much to see and do, having one will definitely make your trip all the more memorable. If you can’t wait to venture out into the great outdoors, opt for a vehicle with a little extra power. A full-size car or an SUV could be just what you need. A smaller car, like a mini or a compact, is a popular choice if you’re only taking shorter trips.
