Well executed 5-S are rare. I'd suspect Hall, Dennis Quella, Don Byars. The interior makes me suspect Hall. One up-close look at the paint would tell you if it was Hall or Byars. Picture on Provamo reveals the car had Kinesis wheels at one time, which is a clue it might be Quella. I've seen that engine compartment before with the stripes and Pantera GT5S wording; just can't remember where or when.
