When I first bought my car I was told it was IB. After I got it, I found out it was LMB (looking under hood at the VIN Sticker). I love the color. It is a deep rich color and I have no regrets either way. I have a black Novillo interior with Carbon Black Trim. Yes, the paint swirls fairly easily and God help you if you need body work. It will probably be hard to match as the years go by. But, it is a great color. I love washing it and seeing it nice and clean.
