If you ever go with the Forester, BTW, I would be interested to hear about your experience. It's a vehicle that interests me.
One of the things I find about desiring a Vibe replacement (again, with my wife in a new car, I'm probably a few years away), is that everything that suits my wishes winds up being larger. The Prius V, the Forester and the Kia Niro (suits my wishes, but some of the stuff I read online suggests it could use another model year under its belt) all seem a fair bit bigger than the Vibe. Maybe not the Impreza, but I recently sat in one again, and I don't think it's quite as comparable to the Vibe as I thought it was, in terms of interior room.
It's not a bad thing, but in the interest of economy I'd be happy if someone could just throw some brand new innards into a slightly restyled Vibe body. (Honestly, I'd be perfectly happy if it looked exactly like a first-gen Vibe).
