I've stopped and looked at the listing on this one several times:

More work to bring back right than the 993 body and the take off parts would be harder to sell, but $30k for a 3.6 swap with Wevo built 915 in it. For a paint and body specialist who wants a targa this one is worth saving.
Though there might be that oddball collector who likes the provenance of that blight as it sits and wants to put it into a collection. To me it's just another '73 911T dolled up like a hooker on Saturday night.
