Well, some of the pollens and saps can get pretty sticky and screw with your paint if you let them build up. Plus, I love cruising around in a shinny clean car on weekends like the one we just had... I had the girls out in their bikinis washing my car with me yesterday...heaven.
I've grown used to the dirtiness of it living in Augusta for most of my life. I just can't stand all the sneezing that comes with it. I was so happy when I came back to the city after spring break.
i hate pollen season but if you have a light colored car like me you get to see what it would look like in yellow
