Okay maybe I'm being too harsh...
Some of those do have some aesthetic merit, and I have seen my fair share of alright/nice ones (AFAIK on Youtube), however I still stand by my opinion against custom ones that generally and most likely low quality.
That one in the video looked only suitable for Nissan Skyline skins for the XR, and I bet that only the XRT was available, which again, (by Patch Z anyway) demo'ers don't have access to.
