Car/4WD hire

To rent a car in Germany, you'll need: Driver's license. International Driving Permit (IDP) Valid ID (Driver's license or passport can be used; for non-EU visitors, an International Driver Permit is required if your license is not written in English.)

Lower payments: The monthly loan payment for a car you own is generally more than a monthly rental payment. No fees/taxes: Standard expenses include taxes and fees at purchase and registration and inspections every year when buying a car. You're not responsible for any of these in a long-term rental.

As long as you have not taken up normal residence in the Federal Republic of Germany, you may drive or ride motor vehicles with your valid foreign driving licence for an unlimited period.
Rental cars are slapped with Germany's 16% Value Added Tax (VAT), registration fee, and airport fees (but rates do include the required third-party liability insurance). These additional fees may equal up to 25% of the daily rental.
