Go to the dealer and talk to them. They have powers that you don't have online. Also, you can have them program the daytime running lights so you can use them or NOT. This is a common software setting when selling vehicles to anyone in government.
I started at the dealer and my salesman wasn't very helpful. I think he means well, but he didn't really do anything until I asked him a few times. I might have to try another dealer, but I didn't want to go that route since I've been to this dealer, previously, when I purchased my current vehicle from him.
Also, I don't really want to wait 16 weeks (or longer) so that's another reason why I don't want to order from the dealer.
To be clear, I have no problem using the chevy site builder to give me a list of models that match my criteria. I've found at least 5 vehicles that are local that I would buy other than they all have rear seat media which I don't want.
That being said, I still can decide on a few things which is also keeping me from custom ordering one even if I did convince myself to wait the 16 weeks.
