Theft-Proofing Your Rental Car
By Rick Steves
Thieves target tourists' cars — especially at night. Don't leave anything even hinting of value in view in your parked car. Put anything worth stealing in the trunk (or, better yet, in your hotel room). Leave your glove compartment open so the thief can look in without breaking in. Choose your parking place carefully. Your hotel receptionist knows what's safe and what precautions are necessary.
Make your car look as local as possible. Leave no tourist information lying around. Put a local newspaper under the rear window. More than half of the work that European automobile glass shops do is repairing windows broken by thieves. Before I choose where to park my car, I check to see if the parking lot's asphalt glitters. In Rome, my favorite hotel is next to a large police station — a safe place to park.
If you have a hatchback, leave the trunk covered during the day. At night, roll back the cover so thieves can see there's nothing stored in the car. Many police advise leaving your car unlocked at night. "Worthless" but irreplaceable things (journal, memory cards full of photos, etc.) are stolen only if left in a bag. It's better to keep these things with you, or if need be, lay them loose in the trunk.
Be alert to "moving violations." In some urban areas, crude thieves reach into windows or even smash the windows of occupied cars at stoplights to grab a purse or camera.
