My Father-in-law had a 2002 Sephia, owned it for 3-4 years and only put brakes and a starter on it. It always started, got 30+ mpg, and would fit 4 adults somewhat comfortably. He recently traded it in for a newer kia crossover SUV.
That being said, I would never own one myself. There are plenty of Toyota and Honda cars out there that are much more reliable, better built, and just plain nicer.
