Our 2003 has 102,000 miles on it, and it's a HARD 102,000. It's been almost entirely city, stop and go, cart the kids around, carry the dogs in the back, go to Home Despot, tow the bike(s) to the track car. It gets very few highway miles.
After 10+ years it's been a very good car. I've replaced the alternator and this weird plastic manifold for coolant distribution. Those have been the only issues other than regular consumables (oil, tires, etc.)
I would buy another one without any reservation. Like you, the foldable third row seat with rear a\c vents is great for carting the dogs around.
