I've thought about keeping S2k and picking up a hatch in addition, but:
1. I'd 'spend' about ~$4k if I sold my S and bought an MS3; I've thought instead about keeping the S and buying a '05-06 CRV, for around 18k. So cost differential is 14kish. Again, might now seem like much when looking at housing (esp in SoCal, unfortunately), but the more I save...
2. If I have both the S and the CRV, I won't be able to take the S out as much as I'd like - mostly in the CRV with the kid and wife. Before I sold my daily driver (civic hatch), we would take it on trips, and I'd often think "I wish I could be driving my S". Same would apply now; we're thinking about heading out to Yosemite, but it wouldn't be in the S (no space for camping gear, let alone my climbing gear. Oh, and room for food would be nice to have too). So.... maybe the MS3 is just more (shudder) practical and (shudder) good enough - no offence meant. I could easily fit all our stuff in there, and I'd be fun to drive in the twisties.
btw, anyone out babyseats/carseats in here, and how well does that work? I haven't searched the forums yet, but thought I'd ask.
As you all can see, right now the practicality of the MS3 most likely will win out over the pure rawness of the S - for now. Ask me in a few years....
