If your 230SL is a left-hand drive automatic, your vin should begin "113-042-12-xxxxxx, with the xxxxxx being the actual chassis number. If it is a manual transmission the "12" will be "10" and if it is a right-hand drive model the numbers will be "22" or "20."
There is a very good chassis plate decoding tool in the forums. Just do a search for "chassis plate."
