This car was also seen to good effect in the 1970 produced, but 1971 released ITC 'B' movie, The Firechasers, starring Chad Everett, an American actor who also owned a Cobra in real life, CSX2515; originally finished in Rouge Iris, but later repainted by Everett in a dark silver, carrying the California registration number PGE667.
Ordered new by Everett from Hi-Performance Motors Inc in January 1965, he kept that car until 1975 and it was later purchased by Lynn Park in 1985.
I believe 6018 also made an appearance in the 1973 Twentieth Century Fox production 'Digby, the biggest dog in the world', once a stalwart of childhood Christmas day mornings on ITV in the late 1970's and starring Jim Dale.
