John Song still has the cocoa brown convertible. He also has a 240 or 280 in bright yellow that is truly one of the nicest I've ever seen. Those pics of John's are from a meet last year. I talked to him quite extensively.
As for Erwin, he sold his car from what I know. I have not seen or talked to him at all. John stays in touch with him and I *think* he bought a Hummer. I believe he did it all up with wheels and chrome and the whole shot.
