one family vehicle?

Since we really only use one vehicle regularly, Andy & I are thinking about just having one family vehicle. Thoughts?
The hardest decision will be deciding which one to keep, or if we should invest in something in-between the two. In all honesty, both Andy & I would love to get a black Rav4 since it's small enough for me to drive but big enough to transport animals and stuff while traveling. I guess I have a few months to figure it all out... fingers crossed that nothing more goes wrong with either vehicle until then.
