Unless the bidder magically has the correct EUN serialized WQ block for that car would 16K make sense.
There is not one usable panel on that car.
If one were to rebody that RA car WITH the correct engine would the bid price be worth it.
Just from looking over past 3 days, there is at least 50k worth of bodywork, paint, and other work to be had. And I am not including an original T/A hood $8-12k.
I reality, an already restored or an older restored non matching 69 T/A RAIII could be had for 60-75K
Maybe the bidder has amassed scores of parts, a correct WQ block and has a 69 body. That would be my guess.
Or you could save the 75K and buy a 2015 Z/28
