Yes, I saw the order guide at my local dealership , and the tan is that of the Solstice, an unattractive tan/black hybrid. I thought it would look swell, the tan, as in the saddle colour of the Ferarri, but-alas!-it is a bastardized mixture.
The Solstice interior is steel/sand and is totally different from the
tan going in the Sky.
I am sure of this because I have the Solstice and ordered the Sky with
tan interior and top. My dealer has a Pontiac and a Saturn dealership
so it is easy to check the actual codes from GM to see the difference.
