hello once again. as you can see I am new here. I have a M6 on order and will be in on may 5th. Its steel gray 6s, with sports package, bose, comfort, pretty much all options. Well, i am very anxious to get this car. all i do is think and dream about it!! so you will probably hear me ask some weird or stupid questions like this one here...I was just wondering how the brake dust was on the wheels. some cars leave brake dust on the wheels shortly after cleaning them. does the mazda 6's wheels stay pretty clean for awhile or do the wheels get dirty fast?
