Tehama Leather - Colors for 2007?

My wife has a 2004 SLS which I hate because it has the rock hard, european style seats. I have convinced her to trade it in on a 2007 DTS with the performance package, sunroof, navigation, and tehama leather, or a 2007 Corvette convertible (which will still be worth $60,000 in 5 years). We are leaning towards the DTS as we already have a 2004 'Vette, but then we also have a 2005 Z-71 Tahoe when we need more room.

I have been to 6 dealers and none know in what interior colors the Tehama leather option is available. I have a 2006 DTS brochure and the only color it shows for Tehama is a dark brown, but I have seen references to shale (gray) Tehama and cashmere (tan) Tehama.

No one has a 2007 DTS brochure and even one promised by Cadillac never arrived. Cadillac's "Personal Assistant" service s**ks.

I can't even find a single photo of Tehama leather.

Can anyone help me get some information on the 2007 Tehama leather option for the DTS?

this site lets you configure and stops you from configuring something not available so you could go through all color choices and see which ones are not letting you select the tehema leather seats.....
