I've had my Matrix for just over a year now. It's a great little drive. Combined mileage is 28 mpg for my automatic. I get plenty of power for highway acceleration. I coach soccer and the hatchback lets me haul all my gear, including 5 foot corner flags. The fact that you can fold down just part of the back seat is very convenient. My only issue is the driver's seat back support. I'm used to a minivan with big soft comfortable seats.
Cargo area with the 60/40 split back for easy fold down options. Good gas mileage. Low tire pressure warning light is handy. Fun to drive (says my teenage daughter).
More comfortable driver's seat with better back support.
