Robert Goulet (Broadway, film musicals) owned a Charger Daytona for a time when it was new.
Michael Madsen (Reservoir Dogs) owned a 70 Super Bee.
The bass or guitar player with the Bob Seger Silver Bullet band is a huge Mopar fan for years. Several of them including a Hemi Dart.
Don Coscarelli (Phantasm writer-director) owns the Cuda from the second film.
Can't remember if I read it in an interview or saw him mention it on TV but Jay Leno spoke of having a Duster 340 as a daily driver back in the seventies, early in his career.
Jim Morrison owned a 67 Corvette Stingray ragtop or GTO ragtop early on but crashed it on one of his wasted late night drives in LA. It may even have been the aforementioned GT500. No mention about a Charger but it's possible. The books on the Doors have many individual (possibly hazy) memories. I'd be surprised if he even had a valid drivers license in the later years. He was living in Paris, France the last year or so of his life.
