Had some delays, but I'm still here---I now have every stage, but am only "up to the 50's" in the build still----needed a few replacement pieces (and still need a few more--I'm finding lots of tiny bubbles/pin-pricks in the paint of nearly half "the red bits", while others arrive flawless) I've tried to polish-repair as many as I can, and that takes a lot of my time for this kit---those would be the "delays".
Anyways, something that 99% of Countach models miss, including this one, is a "triangle of black paint" that runs from the top of the rear side-window, down to near the bottom of the intake. If a real Countach lacks it, I presume it's been repainted, and they forgot it. Photos of the real red Wolf Countach show it, across several decades. It looks to me like the prototype/sample model for this kit has it too (the finished example in the instructions), but the production pieces lack it. So, I started masking it off, to spray it on myself. (More pics later, once done---this is literally "piece of tape #1" to start)
