The sprawling southern California mansion featured as the Clampett family's home on the 1960s sitcom "The Beverly Hillbillies" is up for sale and is now the most expensive property available in the country.
Perenchio subsequently authorized substantial upgrades and addition to the house, and in 2016 he purchased an adjacent parcel previously owned by former President Ronald Reagan and incorporated it into the property now up for sale.
The home went on the market after Perenchio died in May at the age of 86.
The main residence of the $350 million estate has only traded hands twice before this.
Perenchio bought the estate, named "Chartwell", in 1986.
These days - even factoring in inflation - the Beverly Hillbillies' newfound oil wealth of $25 million could barely cover a down payment on the home. The asking price for the Bel Air estate, known as the "Chartwell", is on the market for $350 million.
Built for entertaining, the residence features a wine cellar, salon, ballroom, and period-paneled dining room.
The estate's grounds, which span 10.3 acres, also include manicured gardens, a tennis court, covered parking for 40 cars, 75-foot pool and fully equipped pool house.
Chartwell is now on the market through Coldwell Banker Global Luxury, Hilton & Hyland and Berkshire Hathaway Home Services. The brokers announced the listing through a spokeswoman Monday, but have not yet entered the property into the multiple listing service.
