F'real they're just better SUVs. I tried googling it, but the internet's very helpful answers were "they're not cool" and "SUVs are more popular." I'm convinced it's manufactured desire. What really happened to the minivan?
Edit: Apparently wagons and minivans still exist, they're just sold as SUVs.
Toyota Sienna and Honda Odyssey are still made
Also the Chrysler Pacifica /Dodge Grand Caravan and KIA Sedona/Carnival
