So, I'm on the more mature side (older) and have owned probably a half of dozen black cars in my lifetime. I would buy one, get thoroughly discusted with the speed of dirt accumulation, and sell the car. After approximately 6 to 8 years, l would forget about the PITA constant cleaning (one of them was a show car), and l would buy another black car, and the cycle continued until my purchase of a black lr_awd Model 3. I loved the car so much that l put up with the dirt for 14 months before l traded it in on a WHITE Model 3 Performance. I don't think I'll ever buy another black car again... but who knows (never said l was a genius).
BTW, l don't think anyone else has mentioned this, but it appears that birds love black cars to make their deposits. I've read somewhere that they like think large dark shinny objects resemble water, which is supposed to be attractive to birds to release their excess waste. I'm not sure how true it is, but l can attest to the fact that all my black vehicles seemed to accumulate more droppings than any other color cars I've owned, particularly right after washing/waxing!! Lol!!
