I've only caught the high points from the thread so far. I will go back & read the entire thing shortly. I know enough to throw in these two comments & may edit this later.
First detail for the sake of detail is fine if that is how you build. Detail devoid of accuracy? Again fine, but don't be surprised if someone points out that a power steering pump doesn't get plumbed to an alternator, that an automatic transmission doesn't have external linkage like a manual or that you used Chevy headers on a Ford motor, etc, etc.
Second it is not anyone's place to tell someone how to build or demand accuracy from a "super detailer". However when builders are held above others, given much coverage in several model magazines those builds should feel some responsibility to get it right. When you are put in the spotlight of the hobby, whether it is deserved or wanted, you become a representative for the hobby and will be held to a higher standard by others, especially those outside the hobby but have an interest in models & automobiles. Many peoples opinions are already jaded & think we play with toys. Extraneous, non-accurately detailed models will do nothing to dispel that generalization.
A little extra time spend researching your build can pay big dividends in the future. Besides once you learn the basics of wiring & plumbing engines for example, you don't have to re-learn it for every build, just tweak the specifics for manufacturer, displacement, etc.
