New Wheel
After five years, the outer covering on my Corolla steering wheel began to flake off. The surface underneath wasn't as comfortable to grip and the edge of the flaking was rough, almost sharp feeling.
So I bought a leather steering wheel cover from Wheelskins and sewed it on myself. The color did not match what I saw on my monitor—the real item was lighter in color—but the color worked well, maybe even better than what I was expecting. (Wheelskins will send free color swatches so you can get a better idea what the real color will be.)
Here's a photo of the cover on my steering wheel:

It's really fun to drive now, almost like having a brand new car.
