Built in 2007, this waterfront property in sporty Lake Arrowhead (about 80 miles from Los Angeles) boasts a garage that is bigger than most mansions. At 8,000 square feet, the 22-car garage is similar to Jon Huntsman’s Deer Valley behemoth, but the California version contains the highly coveted car turntable. No we’re not talking about some sort of automobile-DJ (although that would be cool). Instead, the turntable is at the center of the slate-floored garage to ensure easy parking for your billion-dollar car collection. The garage is also surrounded by a 1,200-bottle wine cellar, adjacent tasting room, and its own bathroom. The rest of the 16,000-square-foot abode contains everything you’d expect from a megamansion: 11 bedrooms, 17 bathrooms, 2 game rooms, and 2 elevators, all with views of your private boathouse and 2 Trex docks. As Lake Arrowhead’s most expensive property, it doesn’t come cheap at $13,900,000, but that’s a steal from its original 2013 listing price of $15,900,000.
