Has anyone tried to add the Black Design Pack after market? I am having a hard time finding a CPO 2016 DS in the color I want with the Black Pack and was wondering if anyone has tried adding it after the fact? I know the wheels are easy to do with powder coating and there appears to be 5 or 6 components you would need to purchase for maybe $1200 US. Just curious as I am trying to decide if I wait for one to come on the market or buy one without the pack and add it on. Thanks for any input.
