There were a couple threads a while back from folks asking what accessories they would recommend when ordering their new CT. I have the Premium with 6-speed MT. I ordered my accessories separately instead of dealer install because it was cheaper. I installed an auto-dimming mirror (so I could wire in a dash camera using the little jumper connector). I wasn't sure if I needed an auto-dimming rearview mirror, but now I don't think I can do without it! If I had to order my car all over again, I would try to get the auto-dimming side view mirrors as well...not sure if that is possible with my 6-speed. I absolutely love the auto-dimming mirrors!!!
