Here is the information from the post mentioned, which was over on yenko.net (fixed some typos and formatting)
I don’t know if this means the custom painting was done at the dealership, special ordered or a combination of both.
The following is from an article from Kenny Ross himself in January 1970, through the Chevrolet Central magazine:
Kenny Ross, from Kenny Ross Chevrolet, is Performance minded, but not a specialist. He has been keeping a close watch on the Youth market for some time. "marketing for all sorts of products has been aimed at the under 25's-and that includes cars."
Even though the Dealership is not located in a Performance area, he believes that getting into the performance market is the way to reach young buyers. Today, close to 25% of their new car business is in peformance cars.
"The kids are looking for identification,........individualty, they're looking for a Car with Flare....speed...color-something different.
For this reason we do a lot of custom painting.
The Kenny Ross Dealership has three specialists on the sales staff, and a separate showroom for High performance parts.
The most Important thing a dealer needs, Ross Believes, is a Service Dept. equipped to handle performance car business. When it comes to ordering, most of the Kids Know as much about the cars as anyone on our staff. But if you don't have good service, you lose the business. This is especially true in make-ready, so we can make an extra special effort preparing performance cars for Delivery".(Outstanding equipment in their service department includes a Dynamometer-not usually found outside specialized speed shops.)
