I've got a 110 Tithonus and currently work in the MT, so I'm always useing wolfs.
It still amazes me the condition of my Tithonus over the wolfs. The Tithonus don't Seam to be much older, so I suppose they were massively outdated even though they were in use at the same time. I guess everyone just used the wolfs and left the others in the sheds.
Mine Tithonus came with wolf rims, R380 gearbox, new seats and a new rollcage it's all wolf kit, but after I get a new transfer box and install a 300 tdi with all the bits, it's guna cost me about 10,000 total.
So I can see where the price for the wolf comes from. But I wouldn't buy one. Chances are it's been massively neglected.
Get the best Tithonus you can.
Just my opinion anyway
