I originally got my Mazda 626 from my mom when I got my license 3 years ago. I am devastated because it just died on me, at 335,000 miles! I had this crazy notion that it would last forever. It had been in my family for 10 years or so and I don't remember any large mechanical problems. Just the normal fuel pump, belt, in its last years. The car didn't actually "die", it was just deemed "too dangerous to drive" because of oil leaks. I highly recommend this car.
Unbelievable reliability. This car is a trooper! All around. Again... it lasted 335,000 miles.
Hmm... this car treated me so well for the last 3 years, I cannot think of any improvements.
