OK, I found what I was looking for... While I was mistaken in thinking it was Don who wrote about Ourisman, it was actually a copy of an article about the Yenko Stingers that Don included in a packet of info he sent out to a potential customer. Dated Feb 1 1968. The article he included was written by Bill Barnett and was titled "A Trip to Stingerville". I attached the portion of the article that references both Ourisman Chevrolet and Rosenthal Chevrolet... its tough to read, but the actual excerpt reads "Yenko is a small Chevrolet dealership when compared to an operation like Ourisman or Rosenthal, but more efficient and close knit than any dealership I've ever seen."
