This is a nice van and is our second Grand Caravan. We bought the Special Edition with a few extras and it has proven to be better than the '02 we had. I have not yet put out on an extended trip, but in town it is getting 18 mpg, which is what I was getting the our '02 on the highway at about 85mph. We just bought a new house and the Stow-n-Go seats came in real handy making several trips and not having to move those heavy seats. The power doors and rear hatch are a nice options to have. I have not even noticed the decrease in horsepower, and the engine sounds stronger. For the money you cant beat this van with features that cost and arm and leg from Honda and Toyota.
Make the power passenger seat adjust up and down. It sits very high. I'm 6'0 and have about an 1 in from the roof. Improve the sunroof. When opened fully at about 30 mph it kills your ears. Its a big roof so leaving about a half in form full still looks normal.
