Most people looking to rent an SUV with a 4WD are often disappointed. It’s not that easy to find this type of vehicle to rent. You can check websites of some of the most popular car rental agencies, but you may come up empty-handed. Logistically speaking, the systems can’t identify a 2WD or project a 4WD whereabouts at any given time. Rental companies will need this filter so that people can rent it.
