Haha, no. I'm not the one trying to justify my automobile that needs to be described as "loosely associated" with adventure travel through some sort of cause and effect (if I sell my regular car, I can buy an adventure vehicle). But hey, if Expedition Portal is cool with it and it falls within the spirit of their rules, then who am I to say. When priced correctly, vehicles move pretty good in this section, so if regular, high mileage cars with needs are appropriate, I'll certainly keep that in mind later down the road.
Either way, GLWS!
