Do check out this nifty little video about a special edition Haynes Manual, from one of the most prominent providers of online auto repair manuals. It's an Owner's Workshop Manual for the U.S.S. Enterprise, or that space ship in the Star Trek universe if you're not familiar with it.
It's not exactly an online auto repair manual, really, but I think it's fun that Haynes is recognized enough that it gets to produce an official licensed product like this one because of course it is a widely known publisher of manuals and similar reference materials.
The official info states that it took two years to make the manual, so there really was a lot of work put into this to make it look like a legit manual. The manual was released last November 2, 2010, and it is available in both e-Book and hardcover print formats. The manual contains detailed technical information about the different fictional spacefaring vessels that bore the name Enterprise, along with cutaway internal views, interior focus, and key system information. The book has been authorized in full by CBS as well as Michael Okuda, the technical consultant that had been part of the team that worked on the TV series Star Trek for 13 years.
