Car enthusiasts — from the humble vintage Chevy owner to luxury collectors like Jay Leno or Jerry Seinfeld — would be envious of this sprawling Atlanta home. The 40,000-square-foot horse barn-turned-garage can fit up to 70 cars, something the current owners of Tanner’s Mill are taking full advantage of. The garage, which could probably be considered a “showroom,” is dealership-themed, complete with its own fake gas station and storefronts. Overlooking the private “dealership” is an entertainment area. The listing from TopTenRealEstateDeals.com says you could convert the garage back to into its original equestrian center, but we can’t imagine why you’d want to. Besides the garage, three caretaker homes, sprawling pastures for horses and a large lake surrounding the property, the 12,000-square-foot main house is equally impressive.To get to it, one must travel over a covered bridge and up a long, winding driveway. The grand entrance features both a waterfall and a pond.High vaulted ceilings with wood beams and reclaimed hardwood floors are just some of the pieces of the home’s rustic charm. A formal dining room, family room, game room with a wet bar, chef’s kitchen and butler’s pantry make up the first floor, in addition to the main-level master suite with its own living area — complete with a double-sided fireplace. The house has five bedrooms and five baths in total. The back of the house features a massive wrap-around porch that allows you to enjoy magnificent views of the property and its surrounding river. It’s perfect for outdoor entertaining, as is the lower ground-level terrace. For $16.5 million, you can purchase the home and 446 surrounding acres; for $9.9 million you can get the home and 136 acres. According to the property’s exclusive real estate agent, Debra Johnston with Berkshire Hathaway, some of the cars will be sold separately: if you were so inclined to fill up that garage quickly.
