The GT seems to still have ambient lighting, just not dynamic ambient lighting.They want to move people to the DE. I see no other reason. Yet, we bought with the understanding of having the Tech package. I can live without HUD I suppose, never had it, wanted it, but can live without it. But eliminating lighting? Something countless high end vehicles have as standard? That's a cheap ass gut punch.
It lists ambient lighting for the Standard Exterior and Interior Features option in the Comfort and Convenience Package package.
