I bought one of those from that ebay seller about six months ago for my W123. It was cheaper, but the exchange rate might have been better at the time.
On the down side, the leather covering looked cheap and not brilliantly stitched and it is an expensive mod.
On the plus side, it turned up (quickly!) it was easy to swap over.
It complemented the zebrano trim excellently, and felt great in my hands when I was driving.
If you get one, keep the old steering wheel. You'll want to sell it separately at some time in the future.
And, when I was changing it over, I had to do it a few times, because I hadn't quite aligned it properly. Make sure the front wheels are dead straight. HD
