One Lap of the Web: Antarctic hot rods, Nissan BE-1 for sale and parting with a beloved Wagoneer

Fisker to buy former GM Solstice/Sky plant in Delaware for $18 million

The old General Motors plant in Delaware that until July cranked out sports cars for Pontiac, Saturn and Opel will be sold and retooled to build plug-in hybrids with UAW workers.
