Decode This!, the classic car VIN decoder site adds 1960 and 1961 Oldsmobiles to the cars that it can decode.  More VINs will be added as they are data entered.

Decode This differs from other VIN Decoder sites in that it can decode various makes and models.  Currently it decodes all Fords and Chevrolets between 1960 and 1969, plus Mopars from 1966 to 1972, as well as various other models.  Definitely worth looking into if you're curious about your classic car's history.
