2007 Toyota Matrix Hatchback XR 4dr Hatchback (1.8L 4cyl 4A)
Second Review.  Got rid of it.
 While the gas mileage was a definite plus, the lack of power in this vehicle and the size of other vehicles when driving the Matrix, made me get rid of it.  I didn't have any problems with it mechanically.  I guess the 4 cyl ran as it was supposed to.  I haven't had a 4 cyl for years so maybe it is just me, but the car lacks power and is loud.  Low profile made for uneasiness driving in rainy weather.  Being in Western PA, I felt that I should get rid of it for when it snows.
