Believe it or not, compact cars are the most commonly booked rental car in Brittany. And if you're thinking of spending the majority of your time cruising around the hectic streets of Rennes or Brest, you'll quickly see why. Ditch that huge SUV for a set of wheels that are compact and zippy --- parking is a snap and they're fun to drive!It's always fun to head out of the city, and if you do, you'll be handsomely rewarded. With cliffs, bays, and rocky coastlines to explore, Brittany offers plenty of day trip opportunities. A larger vehicle like an SUV or a four-wheel drive will give you and your passengers more space for those longer drives.
