Dirty steering wheel
I've been called a little "anal" before because of it, but I keep a pair of "Mechanix Wear" gloves in the truck just for driving, because I've seen too many wheels with that thin leather cover dirty, and worn and I don't want to have to spend big$$$ trying to replace it.
I bought and installed an aftermarket cover, and hated the way it looked, and fit so it now resides in the bottom drawer of my toolbox.
