I have just purchased my Matrix and I am thrilled about it. A friend has one & she loves hers also (one of the reasons I bought mine). It is stylish, gets better gas mileage than expected (38 mpg) and fun to drive. Not a lot of pep but knew that going in - I'll take the great gas mileage any day. Wanted a white one, got a dark grey and it is just beautiful - glad I didn't get what I thought I wanted!!!!! Lots of space inside - front and back seats and hatch back is awesome!
The styling, the roomyness, the hatchback, ability to put passenger seat flat for hauling long things.
I have basic Matrix with power package - wish I had power outside mirrors (no big deal) and map lights.
