Ive had two black cars and would def buy another, I didn't find Black to be any more care intensive than any other color though I did use some formulated for black specific products. The only time I think it was any kind of an issue was i had black on black on black and would get pulled over for my tint, which measured at ~35%, (the legal limit) and the Deputy would look at me all silly, ya the whole thing is black, black paint, interior, wheels, so the tint does appear darker than it would measure"...
