A unique Napa Valley home is set to be auctioned off on September 10th. The 22,882-square-foot Villa De Madre was originally listed at $22 million in 2011. Now the seller, Willis Johnson, founder of Copart, Inc., a publicly traded, global online vehicle auction company, is holding an auction instead. The gated property in Suisun Valley includes nearly 80 acres, a caretaker's house, three auto barns, and 63 acres of Cabernet vineyards.
