I would never let my wheels get that dirty. How we maintain our cars is a direct reflection of who we are as people. I would no sooner let my wheels get that dirty than I would work under a car all day and then go out for the evening without taking a shower and changing clothes. Now don't get me wrong.... I am not totally **** about car cleanliness, just as I like to wear jeans and casual clothes instead of a suit and tie all the time. I have been know to wear a baseball cap, just because I did not want to do something with my hair. So, yes..... cars get dirty..... sometimes we don't have the time to ensure that our cars are meticulous, but I think there is a line that we as individuals have to set as to what is too much. That line will be different for each of us, but it will speak volumes to others as to our personal standards.
