I do remember the Barnes car with the paint scheme you mention, but have no photo's of it. The add on flared guards and front spoiler look similar though. I think this car was driven by Reda Awadallah. His family owns Blue Haven Pools and he did drive Sports Sedans later on with Blue haven Pools sponsorship.
Mean while here are a few Trans-Am Mustangs.
Steven Johnson in one of the first Trans-Am cars to make it over from N.Z. Shane Drake drove another one at the same Eastern Creek meeting.
