There were only 15 Pontiac Motorsports chassis produced, 6 of which were Fiero’s that raced in IMSA. This car was build as an after hours project between Terry Satchell and Greg Seyfert. It was campaigned by Seyfert and David Buist in 12  IMSA events between 1885 and 1987 in Miami, Columbus, Summit Point, Road America, Pocono and Detroit.

The car was restored in 2006 and given a Chevrolet LS6 V8 and a Porsche 930 based transaxle.
