Was only discussing this with Brad at Enhanced Automotive the other day post my engine bay wiring loom issue. Not sure if you saw the thread, but I got the last wiring loom in existence from a country Vic Holden Dealer. My 12 year old loom was fried, I am talking snap like a twig in places fried. The car was constantly throwing TB codes and going into safety mode, so basically undriveable and only due to Brad's expertise and persistence did this get rectified. But long story short, if this happens to someone else from what I can see it is bye bye car. There is one bright side for most owners though, Brad reckons cars with top mount blowers are obviously generating a fair bit more heat under the engine bay, so that may have accelerated the process for me.
Other than this recent issue plenty of parts are no longer available new, and super expensive or impossible to source second hand, too much to list if you ask me
