Original Owner 
2004 Toyota Matrix Wagon AWD 4dr Wagon (1.8L 4cyl 4A)
167k Trouble Free Miles
 I just sold my Matrix XR after 162k trouble free miles.  The only problem I ever had with the car was the original battery failing at 6mo.  Even normal maintenance was pretty cheap with the car; (obviously oil, belts, coolant, air filters are really time based and don't vary from car to car) the Matrix was very easy on brakes & gas and decent on tires too.The car drove well with that nice Toyota balance of good comfort and reasonable handling.  The ability to haul stuff is excellent!  The rear seats fold completely flat, the front passenger seat also folds, and you can open the entire hatch or just the glass.  All together, the combined to make a great car for road trips or oven to the lumberyard for 2x4's.  If I could change one thing it would have been power- another gear in the tranny and 20 lb-ft more torque would have really helped (was disappointed with Toyota when the next generation came out and didn't address these issues, they were the only problems with the design).If you're reading this, you're probably looking at a used Matrix... if it's been well maintained, go for it.  It should treat you very well in the long run.
