Car is perhaps in the need of a little clean-up (bumpers etc.)
Look at the (plastic) number plate support: MB dealer from Holledau!
That's the area in Bavaria where (almost) all the German hops for beer brewing comes from!
The chrome bar between the bumper halves is missing, so it "could" be an US or Italian version.
But on the other side the "Automatic" sign is missing on the trunk lid below the (obviously brass-type) 230 SL sign.
Dashboard is dark (black?). So, perhaps the car has not always been silver before (too hard to tell from here).
Sorry, I apologize for my words ...
