The official car of Emergent. This one was a no-brainer. Maybe it's because of the whole enviro-friendly thing, or maybe it's the anti-western / north-american mentality. Either way, those emerging types do like their echoes.
The official car of the middle-class, conservative church family. Okay, okay, so it's not technically even a car. But if you're going to haul around those 2.3 children from your middle-class home to soccer practice, the Montana is a must.
The official van of the Dutch / Christian Reformed. Because when your children number a baker's dozen, there just really aren't that many options.
The official car of the seminary student. Students in beat-up, old cars. How cliché.
I tried to think of more, but that's all I could come up with off the top of my head. Any more suggestions?
