What am i missing??..

Right! It all depends on the vehicle and how bad someone wants or needs it. For most of us, all we want or need is something to spin the engine well enough to fire it off. I couldn't care less about a date code. lol
Same here and I've got a car that it could matter on, but I also want to drive it and not to worry about the minutia. As long as the big things are "correct" that's all that matters to me. But, I also understand those folks that want all those things. They are the reason we have so many repop parts these days...
