I don't own a black car, but my next one will be. Even if it's a DD. My current car is a darker red shade, but as far as I can tell my washes don't really induce any new marring that's noticeable. New marring is made by my friends on the door handle area because they're not conscious of these things.
I've given up the two-bucket system as well, but that's because I now use one bucket + foam gun. I even ordered a CRSpotless so I don't have to towel-dry anymore (it's more of a time-saver for me than anything). If you have a garage and your car is parked during the day in a somewhat non-hazardous environment (covered parking, not too many birds, lots of space between you and the next car, etc.), owning a black car is rewarding I think. If it's outside full-time and subject to extreme weather conditions, then it's just a matter of figuring out if the maintenance is too much.
