For the most part, German rental cars can be driven throughout Western Europe. Italy is off-limits for some more expensive cars such as Mercedes, BMW, and Audi. In fact, a few luxury models are not allowed to leave Germany at all. When it comes to travel to former eastern bloc countries, some German rental car companies (notably Avis) allow travel for a limited number of makes and models—mostly Opels, Fords, and Skodas. You will pay a small premium to take those cars to Poland, the Czech Republic, Slovakia, Hungary, Slovenia and Croatia. However, the price will be even higher and there may additional fees as well if you plan to venture in to such countries as Bulgaria, Romania, Bosnia, Montenegro, and countries that were part of the former Soviet Union. Make sure your booking confirmation and rental contract specify just where you can and cannot drive your Germany rental car.
