Well, the picture I included is of a w126 and it has a newer steering wheel, but not sure of which model. Is the steering wheel in the picture of a stock part or is it a custom made one?

Suginami.. I have seen that site before, however... I am more interested in the steering wheel pictured above instead of the ones they offer.

Also, what sort of work would I expect for a cool project like this? I will be keeping an eye out on ebay for a steering wheel like that.
