What is it?

Mine would be a place right down the street from my house, the owner has it for sale for $879,000 but the house is not what catches my attention. The property has a half mile landing strip and 3 storage garages for airplanes.. throw a dyno in one of those with a couple of lifts and basically I would have a mini Top Gear test track in my back yard, damn I'm going to buy that place one day.
