Assembled: Princeton, Ind.
Percentage Made In U.S.: 75% Japanese automakers not only have a stranglehold on the all-American family minivan -- they're the only companies making them in the United States. Chrysler may have dominated the minivan market in the '90s, but today they assemble only their Dodge Caravan and Chrysler Town & Country in Canada. The Toyota Sienna ( TM) gives families the room they need with the V6 power they want when family road trips seem particularly interminable. The Sienna was the only minivan on this list last year, but its rival stepped up its game a bit.
