    I went to a dealer and tried to order a 2022 Colorado. I built the truck as to what I wanted to order. The dealership placed the order and it was declined. Reason it was declined I ordered a 6 cylinder motor. The dealership was told they are only installing 4 cylinder motors in the Colorado. The 4 cylinder will not meet my needs. Can you help with this issue. Another request. Can you offer more paint choices. Such as a dark blue.

    I will not buy a silverado. It’s to big of a truck. I don’t want to buy another make of truck. It seems I will need to try another make.
