I just found out that Auto Zone has a lot of online repair and specification data on their website for most cars...I checked for E28 BMWs and a lot of it is pretty general stuff, but they do have wiring diagrams, torque specs, etc.
It probably isn't that much good for our cars (since we all have our Bentley manuals handy

) and it's a little klunky to use (you have to click around a while to enter a vehicle and get to the right page, but you don't have to sign in), but if you get roped into working on someone else's car it may be useful.
