Fisker Automotive, a plug-in luxury car maker based in Irvine, California, purchased GM’s shuttered Wilmington, Delaware assembly plant for $20 million. The Wilmington plant last produced the (much-missed) Kappa platform vehicles (Saturn Sky, Pontiac Solstice) and manufactured the Saturn L-series before that.

Fisker plans to build rechargeable batteries at the 3.2-million-square-foot assembly plant by 2012 but will initially use the facility to build its Nina model.

The sale of the plant should add a hefty $20 million boost to GM’s balance sheet for Q2 2010, which GM should report sometime next month.
