This is Twisted Tropical Olive:The Exotic finish is Twisted Tropical Olive, which is no longer available. Aside from that, I wish the seller all the best in garnering the asking price (tongue in cheek).
The kit in the ad is Twisted Rainbow:
I think you nailed it. Same Twisted Rainbow finish with gold hardware, same gold Gibraltar rack with curved riser bars, same set configuration, same gold DW badges. Looks like this is the kit.Tris Imboden perhaps?
I guess if you are a big Chicago fan, then this may be something you want, but surely not for $30k, or even the sale price of $29k.
Just for posterity purposes, here are images of the kit for sale:
