Get your luggage, stroll out of Mannheim Airport (MHG), and pick up your rental car. Which one you slide into depends on where you’re headed. If you’ll be spending the majority of the time driving in downtown Mannheim, around 2 miles from the terminal, select something small and zippy. A compact car with nimble handling will be ideal for navigating those bustling city streets. But with almost endless things to see, like the picturesque caves of the surrounding region, there’s a good chance you’ll rack up those miles. A bigger vehicle, like an SUV or a full-size car, will make lengthier road trips a pleasure.
