Minis are the most popular type of rental car in Greece. Get behind the wheel of one of these economical vehicles and you'll be able to zoom around the sights of Athens and Thessaloniki with ease. They're roomier than you might expect --- you can easily fit your trusty weekend bag in the trunk if you're thinking of heading out of town.That said, Greece is widely known for its dunes, rocky coastlines, and shingle seashores. Many intrepid adventurers skip town to take in these glorious vistas. If that sounds good to you, consider an SUV or a full-size vehicle. Even if you're not planning to wander off the beaten track, you'll be glad you have all the extra legroom.
