Sure, it’s possible to head out and explore Potrero Grande without a car. But with so much to see, having one is sure to make your trip all the more memorable. If you can’t wait to venture out into the great outdoors, choose a vehicle with a little extra power. A full-size car or an SUV will do the job in style. A smaller car, like a mini or a compact, is a popular choice if you’ll only be taking shorter trips.
