Met the man that used to own that car (if there is only one running car). It was in "as raced" configuration then. Long before I met him I saw that car circulate (pouring smoke out the back) around Laguna at the rear of the historic CanAm race. He said the car was so difficult to manage from a systems standpoint (see smoke) that he dared not run it any faster.
Really cool car, just never developed into a real race able vehicle.
