Yenko and/or Chevy experts?

The XP-887 was indeed the New Chevy Vega 2300 for 1971.
In it's infancy they were touting it as the next best thing since sliced bread.
I aquired a large collection recently,and have a few a boxes 3 feet high full of Chevrolet zone & dealer letters,as well as 16mm movies about it's unveiling.The marketing & promotional materials planned for it were serious stuff.Chevrolet saw the Handwriting on the wall with High Insurance rates and Gas prices forecast.
I have yet to read everything,but its hype and enthusiasm were fever rate!
