Hey, just think, minivan equals more room to carry R/C crap to the races.
Unfortunately my wife and I are not blessed with children so we really have no need for the extra seats, although the extra hauling room comes in handy. We rented a minivan when we went to Branson, MO a couple of years ago. Loved the way it rode and handled, plus the room and space to move around was nice. In-laws have 4 grandchildren, so they just bought an '06 Honda Odyssey with the variable piston engine. On their first trip to Idaho they got 26 MPG, not bad for a V6. They had a 2000 Ford Windstar which they say never got over 20 mpg.
We had a 2001 Tahoe and it got about 18 hwy. Sold it 10 months ago and all I have heard since then from the wife is "I miss my Tahoe", although this is the gal riding around town in a 2003 Volvo C70 convertible, so for mother's day I got her a 2005 Envoy Denali. Same V8 as they Tahoe, but 800 lbs lighter. That thing cooks, but only gets about 20 hwy. But so does the Volvo, so either way, she is costing me money in gas. I also have an '04 Wrangler with the 6 cyl. Because I ordered it with the real low gears, that thing sucks through the gas, too, at about 14mpg, and the darn thing can hardly hit 75 mph. Thanks God I have a car leased by my employer. When gas gets real expensive we just use that more as they pay for it all.
