Look at it this way, it keeps you out of trouble and away from the TV.
I'm not near that compulsive. I wash the car several times a week as needed, but it's just a wash. I wax it only a couple times a year. (The paint ain't that good anyway)
I have a brother-in-law however that's about as fanatical as it gets. He has a Dodge Neon RT that is NEVER dirty. Has one of those car-duster things to dust it off when he gets home everyday. Is constatntly waxing, scrubbing the rims, keeps his tires sprayed with tire stuff, ect.
