I'm with Rob, I was thinking chopped 40's Mercury when I saw the title.
But I knew what you were talking about as soon as I got into the post.
I love those cars! (Okay, pretty much
any Benz, but especially coupes and convertibles.
The 560 SEC (I think) played a pretty good part in the 80's Patrick Swayze movie 'Road House'. It's Swayze's character's car in the movie, he is some kind of high paid bouncer/drifter bad ass. At some point he gets pissed off on a quest for vengeance or whatever and gets in the Benz and heads out to the bad guys' house. I forget what happens, they shoot at him or something, but somehow the car ends up flipping and being destroyed in a big way.
