When there was a separate tech package, it came with the chrome accents on the louvered air intakes in the front and lower rear bumper. If you didn't get tech, the air intakes were black. Now, there are still cars being shipped without these accents and I can only guess this is for cars that don't choose autopilot? I saw a shiny new 70D in the Atlanta (Decatur) lot without the accents. I just noticed and was wondering, I actually kinda like the black look, but I might have a bias For reference, this is what I'm talking about: New 70D without accents: Google Photos - - - Updated - - - Nevermind, I just figured it out. The chrome accents only come with cars with the "Premium Interior and Lighting" package. Go in Design Studio, the image changes when you add/remove that package.
