I am a college student from Philly planning a trip to Tucson. I plan on bringing one friend, maybe two. I have a '98 Volvo s70, a decently reliable car, I just don't know if it could handle all of the miles. Also, I have seen on other threads that it's very hard to rent a car if under age 21 let alone 25. Do you have any suggestions as to what to do? I really wanted to go with the fun road trip, but since funds are also low, I might have to fly =/ .
