We have a 99 Suburban. Driving around town, soccer van, about 12 mpg on a good day. Last May we got a 2005 Honda Odyssey. About 17 on a bad day and up to 24 on highway. I loved my Suburban but would not go back for full time driving. We are keeping it because it needs to pull our boat sometimes. The Odyssey has comparable back storage space to the Suburban. P.S. We have 4 kids and I love to have the extra seat in between kids.
