If he LOVES black and is takes into account the pros and cons posted herin, then the bother should not be a bother to him.
I do not take my car to the carwash. The chemicals adversely affect the headlight covering and will turn it brownish or opague. In the extremely rare event that I do to any of my vehicles, I do not let them do perform any towel drying.
I good waxing, allows for a ready clear water rinsing of the streaks that are undeliably more noticable on a black vehicle. But, I would maintain that as possible testament to the flair that may tickle his fancy, black cars do abound and have been around for some time tickling someone's fancy. Purple, Pink, Olive, orange, blue, brown, majenta are not so populous.
Maybe all the cars should have been only red salsa or silver; then we would not have much to talk about so intently and seeming intensly here.
