As of the end of March/early April, spoilers were included with Z/28 equipment. They no longer appear on documentation. The option msrp increased to $506.60. D80 was not added to Norwood body tags at that time. We don't generally discuss body tag specifics.
Only nice people here Mr. Posi. Feel free to ask questions.
FWIW if someone out there has a Z/28 doc in the VIN range N623xxx-N628xxx I would like to see it.
