@Scrbblechick -- I *hate* the big, furry covers! They are so tacky! I used to have a lace-up black cover for my first car -- a 1977 Maverick. The steering wheel was hard plastic and no matter what I did, it would get hot in the summertime. If it rained or was really humid, the wheel would get sticky on the surface. A cover took care of all that.
To me, the main reason to have a steering wheel cover is to keep the sun from shining down on it in hot weather, but a sun shade does just as well for that, and also protects the dash.
