It's reliable. Gets decent gas milage. Has comfy suspension for when you're driving hundreds of miles each day. And most importantly, it looks cool! It's not the fastest but that's why they have RPGs. If anyone else has suggestions here are the criteria.
1. Must be able to do minor off roading
2. Be absurdly reliable
4. Be manufatured before 2005 (story related reasons)
5. Have a good amount of storage space
6. A big fuel tank
7. Decent MPG (the last two are because of going long distances without refills)
