Yeah, I can pretty much stand under it though not absolutely. So I move around bent a little at the neck so I don't clunk my noggin. (
Nothing under there has ANY give to it!)
My son (and his relatively new wife) built a house a couple years ago and, in addition to having room for several cars/motorcycles, he arranged for an 18' ceiling down at the last bay. For laudable reasons...
Working under a car on jack stands has lost all appeal for both of us.
