First of all, there’s an impressive variety of both luxury and economy rentals in Rosario Airport (ROS-Rosario - Islas Malvinas Intl.). What you end up going with depends on how much you want to spend and what you plan to do. Specialty vehicles offer the best in comfort and class. If you’re splashing out, why not grab an elite SUV, or perhaps a flashy mid-size sedan? On the other hand, if you’re just after something to get from A to B as cheaply as possible, you’re better off going with a budget compact vehicle (or something else that won’t burn a hole in your wallet).
