Want proof that old Jeeps — the original military-spec off-roader — were a work of engineering genius? Watch six soldiers drive up, hop out, tear one apart, put it back together and drive away in four minutes.
The most capable military machine is useless if you can't use it. By creating a vehicle with the minimum of equipment it was able to produce maximum results. It was so cherished for its simplicity, the Jeep was given the nickname "Just Enough Essential Parts." It was initially built for the price of about $10,000 a piece in today's dollars. You can't say any of that about a Hummer. (H/t Cliff!) [via Reddit]
