The private club scene has undergone a remarkable transformation in recent years, shifting its traditional exclusivity to embrace a younger, more diverse membership base.

Mark Somen, a strategic advisor for hospitality consulting firm Craft House, says that, aside from club amenities, the personalities behind some of the most popular clubs can also be a draw.

If the Classic Car Club Manhattan subscribed to Hotel California rules — you can check out, but you can never leave — their members would probably be giddy. Because beyond the Porsche GT3s and Aston Martin Vantages, the club we like to call “horsepower heaven on the Hudson” just gave itself a radical $4m makeover.
