I have loved my Dodge Grand Caravan since I have owned it. It is quite comfortable and I average 20 in the city and around 23 on the highway. It has the 3.8 V6. I've driven a number of other vans by other manufacturers and none compare to the ride quality of the Dodge in my opinion.
The open feeling with the captains chairs and the versatility of the mult seat configuration.
Most things I think should have been improved have been so on newer models.
