Steve, what you and I need are Lexus station wagons! Maybe an LS430 or LS460 wagon like the mockups from
http://www.cwwcardesign.com/Unless it is my imagination, hatchbacks are making a bit of a comeback in the U.S. -- they've always been far more popular in Europe. But I'd rather have a mid-size or full-size station wagon that is based on a regular sedan.
Back in 1980, I hauled almost everything I needed to finish a basement in my wife's Honda Civic Hatchback -- everything except the wall board and carpet. I hauled a few hundred 2x4 studs, a vanity, toilet, pre-hung doors and even a shower surround in that little hatchback. It was a sad day when we got rid of the Civic "truck".
Maybe Americans will eventually get over their SUV fetish and return to more reasonable vehicles. Or maybe not.
