I can understand your fears. I have my own with the same interior. I would think that a change in your order would be OK, but having said that it really depends on where your order is in GM's system. You really need to check with your dealer to get his guidance. As for "other" color possibilities, I think zimm888 (IMO) has offered up a good option for the Cyber Gray exterior, but I am not sure it would look good with red. There are several pictures on the Brownstone Int. in the "Lime Rock Green At Last" thread. The problem is that this is a picture too that may or may not look the same "in person". Good luck!Experience/knowledge requested. I have a Crystal Red with Kalahari on order since July 5. I was hoping that the early color representations of Kalahari were not accurate but it now appears that my initial concerns have been realized...the ordered color is rather dark/somewhat orange and is nothing like the C6 beige/tan interior which was a much better match for the crystal red, IMHO. Since I live in Florida, a black interior is not desireable. Gray isn't an option for me either. I'm toying with the idea of changing to Cyber Gray with Kalahari. Does anyone know if a change order would significantly impact delivery date?
