I took a peek at that CL listing and followed the link to the details.
It looks like a fine entry level bike. It's got a fairly relaxed geometry so it's comfortable enough for long rides...yet won't beat you up. And...it can take a rack and fenders, so as rationale: it can serve as a back-up utility bike if needed.
It can grow with you as a rider. (that's always one I use for purchases!)
