Is Black Opal hard to maintain and keep clean? Do swirl marks show up easy? Thanks!

 

I have a new 2003 clk 320 and it is black opal. I have had it about 3 months and love the car. I have always had silver cars and this time chose to go with black opal it does show swirl marks. Getting a darker color takes more care. I used zaino and it help with the swirl marks and I do try to wash it myself I do go throw the touchless car wash but I am not sure if I should use this type of car wash some say that it can make swirl marks. It just take more care but I do enjoy cleaning my car. If I had to chose again on the color I would still chose black opal and the ash interior which I have.

 

I'm not so proud to say this, but my car is the dirtiest car on the block...
It is a very attractive color and I would highly recommend it if you live somewhere it does not rain/snow that often, and if you clean your car often. But the car gets dirty very easily and I have swirl marks and scratches all over the car.
