When renting a car in Florida, you must present a valid driver's license from your home state or country. Your license must be valid for the duration of the rental and must be in English. Renters often ask if their rental vehicles have unlimited mileage. In many cases, a better question is whether there are geographical restrictions on the rental car.
A rental car can have unlimited miles, but that doesn't mean you can drive it everywhere. A good example of where this can cause problems are third-tier discount stores, such as Fox Rent A Car. Here's a rental car in Florida that everyone should know about. This is great if you like driving different types of cars and you can also sit in a car and decide if it's right before you decide.
Also make sure that the car does not have temporary license plates, as police forces in other states can stop it (some new cars are rented before the corresponding license plate has been issued).
