I am not sure of the protocol here, or whether I may give some offense, but I am posting the same basic message on two different boards.I recently purchased a 97 C270 and would like to join an appropriate owner's association. I do not race or group cruise but I would like to support the design association and also have access to technical information.My problem is there seems to be more than one association and I am a bit confused about the relationship between them. Any explanation or illumination would be appreciated greatly. Thank you.
