Hey Mixte lovers!

I've always drooled over the mixte frames, but never had good reason to buy one. Well, now I need a short distance commuter/around town bike that I can leave in the rain (for short periods if necessary). I was going to convert my 1986 Miyata diamond frame, but the costs were going up (apparently, I have expensive tastes!).

I just found this:
http://portland.craigslist.org/mlt/bik/618237274.html

I emailed the seller and it's a girl whom I'm guessing is in college. From our email exchange, it's obvious that she has NO idea about bikes at all. Is this a steal, or can you even tell from what little information is here? She did say that the bike is rideable in it's current condition, so that's a start, right?

I'm going over to see it tomorrow night, but I wanted a better idea of what I should look for from the more informed TE women. I guess for $30, it really shouldn't matter what shape it's in, right?

My goal is a somewhat upright 'around town' bike with fenders, a rack, a front basket and fairly 'rain proof' features (saddle, grips, etc). Gearing is unimportant as the area I'll be riding it in is quite flat and I have other bikes to accomodate longer, hillyer rides. I don't want to spend much as I won't be using the bike much except in the next 6 months (before we move to the boonies).

Thanks!
