The Matrix has worked out very well for me. I live in Los Angeles, and use the Matrix to commute daily from work. I have owned the matrix for about a year and a half, and have not had a single problem since I purchased it. It is reliable, comfortable, practical, and stylish. I couldn't ask for much more.
The design is great, both inside and out. I also love that you can fold down the seats for easy cargo holds. It has definitely come in handy!
The only gripe I could possibly have with this vehicle is that it could use a bit more pick-up. It's not the peppiest car I've ever driven.
