A mansion wouldn't be a mansion without a good-sized garage. At least not in our books, anyway. But this isn't just a mansion; it's a private resort. And it doesn't just have a garage; it has an actual automotive museum. And it can be yours for the small matter of $279 million.

Built by Discovery Channel founder John Hendricks and listed by LIV Sotheby's is the Gateway Canyons Ranches & Resort, which counts among its considerable on-site facilities the Gateway Auto Museum. It's home to a 50-plus-car collection, most of which unfortunately is not included in the sale price.

Two of the museum's cars are reportedly staying: a 1906 Cadillac Model H coupe and a '29 Duesenberg Model J cabriolet – but the rest is going, including its centerpiece 1954 Oldsmobile F-88 convertible concept. That's a bit of a shame, because it's one heck of a collection, as our own Jared Rosenholtz found (and captured in the images at bottom) when visiting the museum for the launch of the new Kia Telluride. But we can think of a few other sets of wheels we'd gladly house in the facility and enjoy on the surrounding Colorado mountain roads.

As tempting as the prospect may be of starting our own museum collection, there's far more to the property than that. Like the 22,000-square-foot/four-story main house, with its eight bathrooms, home theater, banquet hall, four water fountains, massive outdoor pool, and its own five-car garage. Take the guest houses into account and you get 14 bedrooms and as many full baths, set on 8,700 acres of remote panoramic vistas on the Dolores River, near the Utah state line. Good thing it has two helipads on site, because it'd otherwise take about five hours to drive from Denver or Salt Lake.
