Apparently GM had a dark green ZL1 convertible at XXXXXXXXXXXXX.
The car has a tan top & interior and the windshield fence is painted silver.

The word is that it's actually a V-6 dressed to look like a ZL1, but no difference.

The car looks amazing in the color! Why this color is not released for production is beyond me.

Here's some pics:








EDIT: Apparently this car was first shown at last year's SEMA show. I had never seen it before.
