The steering wheel in my W140 looked like a sorry mess. Birds eye maple, but all the lacquer had large cracks in it. It felt nasty to hold.
From a little distance it looked ok:
But go a little closer and we see the mess that this steering wheel was:
I have friends who have all sorts of stuff/crap/great parts just laying around, and one of them mentioned that he had a great birds eye steering wheel for sale. So, considering the fact that having a cracked steering wheel in the most comfortable car to ever be created in the nineties is kind of stupid, you have your hands wrapped around it the whole time when you are driving, I really did not have a choice.
So I documented the process of actually changing it over with some photos. First thing you need is a long torx bit to loosen the airbag. The screws are on the backside:

Here the wheel is removed, only thing remaining are the wires:
Mounting is visa versa, and here are a quick crap shot of how it looks today. Approximately 99% better to hold in your hands:
