Prices can vary depending on supplier, travel dates, pickup and drop-off locations and more. The simplest way to compare prices is to key in your details on Expedia to find some of the best deals on a compact car rental near Estadio Unico Mar Chiquita. When you come across a bargain, we suggest snapping it up early, as prices tend to increase closer to the date. If you're trying to save cash, consider booking a smaller car. Bigger vehicles are usually more comfortable and have added features, but they're often not as economical.
