Wait a minute.... This is my car!
Was checking into the Forum (Corona, bored) to just see this post. Funny.
It's a 66' 230SL. Maroon. Have it for ~20 years. And yes, it was very dirty when the picture was taken. Much cleaner now :-).
I had it with Klaus Nagel (Redwood City) to get some things done (replace steering gearbox, install AC - which works great). Klaus is an old-time Mercedes specialist who really knows these cars. Not many around.
