It has been very reliable. Bought it with 49,000 miles and have put 187,000 miles on it. Transmission rebuilt at 167,000. The most annoying thing haas been the door ajar warning and the incessant dinging until it reaches 15 mph! Other than that I have kept it well maintained and normal repairs have been done -- like tie rods, suspension, ignition coil pack, radiator hose, brakes, wheel alignment. My children say that maybe we were fortunate and got that "one in a million" good Windstars. I don't know. I just know it has been solid!
Roomy, comfortable, good power, big trunk, removalbe seats.
