I had a 2005 Matrix until I was T- boned on driver side after a minivan ran a red light at 50 mph. Car was totaled, but I walked away with all limbs & I was so happy w. the safety of side impact that I bought another Matrix (2007). I love it! City MPG on manual trans. is about 29-30 MPG (I calculate it every so often). I am only 5'2" so I like that the seat raises and I don't have to be too close to the steering wheel.
Seats, Remote Keyless Entry, look of car, hatchback & interior space/room, location of cup holders, easy clutch/pedals to push, great for shorter peeps
More standard interior lights. Take out crumb-collecting coin holder in center console. Make roof rack an option. Make remote beep when locking & make hatchback button faster.
