I ordered the gray interior. I debated a while about the stripes but decided after seeing them in the Official IBM Colour thread. I had a friend (of a friend) at GM check my Order Workbench last week to confirm the TPW was still next week. The stripe item on the order shows "Not Available" so not sure if that is typical for dealer installed items due to the bankruptcy situation. I believe the White stripes would get installed at the factory (or at least prior to being delivered to the dealer).
I feel your pain about the wait though. I can't imagine those who've been waiting since last October...I really don't think I could have that much patience. Although everyone says it worth it.
Hope it's here soon.
