Looking for something that won't cost an arm and a leg? Say hello to the economy car. This efficient vehicle is the most commonly booked rental car in Rhineland-Palatinate (and a dream if you're on a tight budget). Put gas in the tank on the cheap and you'll be easily getting about cities like Mainz and Ludwigshafen in no time.That all said, Rhineland-Palatinate is famous for its snowfields, foothills, and rolling hills. It'd be a shame not to hightail it out of the city to take in those glorious sights. If that sounds like something you'd be into, look into an SUV or a full-size vehicle. Even if you don't have plans to go off-road, you'll be thankful for the extra legroom.
