That depends where you plan to wander. Downtown Metz, about 10 miles from Metz Airport (ETZ-Metz - Nancy - Lorraine), can be a challenge to drive in. Make life easier by going for something small, fuel-efficient, and a cinch to handle. Keep in mind that Metz is a handy base from which to explore many of the dunes in Moselle. If your escape is more about cruising down highways, then you may prefer something with more trunk space and extra legroom. How about an SUV or a full-size car?
