Anyone with or without black diamond feel free to chime in. Looking to purchase a demo model 2015 ATS Performance with the morello interior or a 2014 Buick Regal GS if I can't do the black. Had a black car before and I'm very OCD when it comes to cars as is probably everyone on here. Does the black diamond hide imperfections well since it has that metallic flake? Especially swirl marks.. Any info would be great.
