The German owner has been extremely accommodating with whatever info he had. The license plate number is from a picture of the 230sl circa 1982 that he had sent me
Side story: I tried to be somewhat authentic and created what I thought would be a correct license plate. FN-BAD 230
FN representing Friedrichsahen & Bodenseekreis (which I though was the area) BAD Baden-Wurttemberg (region) and unfortunately I just picked 230 as a random number. I was at a show once when this little Gramma came up and said I love your car & plate an "F-N Bad 230" Oh well.
The German owner still lives in Salem5 near Lake Constance.
