Both BMW and Mercedes don't bother to publish Tech/Shop/Repair manuals but the week after you buy your new Acura you can buy the super comprehensive and well written shop manual that Honda publishes for all its cars. There are a few things I dislike about my BMW ownership experience and this one is right up there with the forcing of RFTs down my throat.
In a few years you might find the shop manual available for your BMW right here:
