Mecum will be auctioning off CSX2601 in May 2009. They claim it to be the Cobra Daytona Coupe used in the movie, Red Line 7000.

UPDATE: I have since confirmed in the 2008 SAAC world registry that CSX2601 was, in fact, used in Red Line 7000. The car was then sold to none other than Bob Bondurant, and was in excellent condition owing to its appearance in the movie.
