Gaud that makes me sick...!!! I could have bought a running Chevelle Z-16 with a 283 stuck in it for $1400 from a local wrecker service that was the same color. Like a fool I passed on it. This was back in 1980 or so. Who was to know.
And yes it was a real Z-16 body because it was missing the top chrome piece of trim across the back of the trunk. I had a roommate back in 1965 that ordered a 350hp blue chevelle with a 4 speed new. It came in just about the same time as the Z-16's came out. In fact he still has the car to this day.
I remember we took a quick trip to Wichita Ks. to look at a new Z-16 on the showroom floor up there because Tulsa had not gotten one yet. It was the same looking car as I had the chance to buy years later. Even the same color. They must have made a bunch that color.
