What car to hire?

It makes no sense to rent a luxury car in Miami for a simple tourist - you will be lost in a stream of expensive cars. Take a compact and comfortable car, suitable for long-distance crossings and go traveling along coastal areas.  Take at least full size (Dodge Charger) or an SUV (something like a BMW X3). In large and powerful cars, it will be comfortable to move over long distances, to transport suitcases, to lie back while moving between cities, and in general, the handling of such cars gives the driver more convenience and less fatigue.
