Hatterasguy, I believe that the answer to your question about the convience(sp?) package is YES. I remember we were looking at a 1993 400sel, which definently had the convenience package, and amg chrome 18s as well, but it needed too many things to make it worth while. We were also looking at a 1992 300sd, which had the convience package as well, but it needed new seat belt retractors (which are another common problem on these cars), an ac evaporator and a vacuum pump controlling the vacuum assisted doors and trunk lid. So If a 300sd has the convience package I would assume the higher models had it as well. When you say "convience package" you are referring to if you turn and hold the key in the driver door one direction all the windows go down and the sunroof opens, and the opposite direction all the windows go up and the sunroof closes, correct???
