This is a no-brainer. The most fabulous black car I have ever seen is the skin on my 2012 Caddy CTS-V. Nothing like sounding pompous here?
The Black Diamond Tri-coat, unfortunately...moan,...is a thousand-buck paint upgrade, so there will likely never be trillions of these on the road. The color only looks like a shiny deep black in shade. But, in the sun, it is Sparkle Plenty (I almost considered a variation for my vanity plate). Not everyone likes Cads, and the power/handling of the V-series is only recognized by car buffs. But EVERYONE makes comments about the color. People come up at stores, gas stations, or roll down their windows while driving by, to ask about the cool paint job. The border check agents always moon over the car, no matter what check point I cross though in New Mexico.
Because of the super-sparkly flecks in the paint, the finish does not show dust nearly as bad as "straight black". Worth the upgrade, for maintenance.
