It looks like the adaptive cruise control was introduced in 2007. I did not find a mention of backup camera on both 07/08 (Edmundscom). Is anyone aware when they started appearing on the cars? I checked (Pais) on one 2007 300C SRT with both Customer Preffered Packages 21X and 2DX (way overloaded with options). There is no metion of either option. If anyone knows the sales codes for them please share the info.
