No, but my father's is--well, actually, his isn't messy, but too packed with little things in every compartment and on the floor, because he "needs that stuff". Tic-tacs, gum, pretzels, hats, gloves, deoderant, etc.--doesn't really impede sitting in the car too much, though.
Mine is usually washed once a week at least, dusted and wiped down daily to keep everything spotless, and the inside is only touched by me and a tissue box in the back seat, so it rarely even gets dusty. Can't stand clutter in the car, hence the lack of extra "stuff".
