I'm looking to rent a car for a month long southeastern Europe road trip this summer. There are two issues with this rental, which is why I'm posting here. The first issue is that I will be 20, and it looks like the minimum age for many agencies is 21. The second issue is that I'm pretty sure most agencies don't allow rentals to be driven to many of the countries that I want to go to. The countries that I may want to include on my trip are as follows: Germany, Czech Republic, Austria, Slovakia, Hungary, Serbia, Romania, Bulgaria, Macedonia, Kosovo, Albania, Montenegro, Bosnia and Herzegovina, Croatia, Slovenia, Italy, San Marino, Switzerland, and Lichtenstein. I'm prepared to rent from anywhere in Europe if I need to, but the most convenient place for me would probably be Munich, Germany. I want either a 7 seater or a 5 seater with a lot of space for luggage. I would really appreciate any help if anyone knows of any possibilities. As I really want this to work out I may even consider buying and then selling a car, if that were the only option. My dates are probably June 27th to July 27th.
