Placed my order last Saturday 9/24 -Lime Rock Green with Kalahari interior, z51 and 3Lt. I was hoping to add black wheels, but somewhere around adding the magnetic ride, the option for the black wheels was blocked by the software. I can't fathom why. The salesman said he's seen that happen when ordering Cameros so it wasn't the first time he's seen this. Still, this seems so weird to me. Any chance this is a mistake? If not, can someone explain to me how simply making the wheels black would change them so much that they couldn't be included with certain options?
