Purchased used w/17K miles in 2000. Has been a great long term value. Minimal cost to own. ES model has everything available at the time. 3.8 ltr has plenty of power @ 180hp. Hauls 7 comfortably. Great on long trips. Live in TX, van has been to CA and back and Orlando, FL and back plus many trips to surrounding states. Avgs 23 mpg city/hwy. Gotten 29 mpg on hwy, avg 25. As of 5/09, have 229K. Rebuilt Trans. at 190K. New Cat. Converter at 185K. No other major mechanical issues, just stuff that wears out-alternator, water pump, pulleys misc sensors and switches, etc. Would buy again but wife wants something different after 10 yrs. 1999 ES model still best looking w/17in. wheels.
Roominess, comfortable seats (ES), low overall cost to own.
None to list here. Most have been considered and improved in more recent models.
