I suppose it bears pointing out too that I rarely have anyone in my car except myself. Occasionally I'll give a coworker a ride but it's very uncommon that I have more than two three at the most. So if a few things are in the back seat it doesn't bother me at all.

The roof rack would indeed be handy, especially for things like fuel. I'm not too excited about the idea of a gas can inside my car! Not safe at all IMO.
