I have a 2007 Toyota Matrix which runs fine, is good on gas and fits two basses but I don't like driving it. There's a blind spot on the passenger side and you can't see the end of the hood- common on newer cars sadly. As far as transporting the bass, you have to rest it on the side and I use a bunge cord to reduce tipping on turns. The surface on the seat back is very slippery, too. The Subaru is much better in the snow which might be especially nice for you. Is the snow melting yet?
Funny you mention blind spots: the bane of my existence is lousy rearward visibility (especially for maneuvering in parking lots/congested traffic). One thing I like about the 1st gen. Matrix is that the window coverage is pretty good at the back corners -- much better than most current small wagons, including the current Matrix.
What exactly blocks your view of the end of the hood?
Snow? Long gone, the grass is green and the trees are in bud. Montreal's only an hour north of Vermont and upstate NY.
Anyway, I've never had much problem getting stuck in snow even with my front-wheel-drive puddle-jumper.
