This is my 5th Caravan. I drive 50,000 miles a year. Just passed 107,000 miles. Had no problems untill 75,000 miles, then several small problems with egr valve and vaccum pump. At 105,000 miles the transmission valve unit went bad, that and the 100,000 mile maintenance items + brakes, rotors, sway bars and tires cost me $3,000. The 3.3 liter engine is holding up well. tires lasted 105,000 miles without being aligned, or balanced.
For the price I think the power, ride, interior comfort, room, noise levels, stereo ect. are good. My mileage averages about 23,mpg.
50/50 rear seat uncomfortable for center passenger. every caravan I've had needed some type of transmission work between 100,000 and 135,000 miles, I wish they were more reliable.
