Carson, you are selling the WIS, correct? Specific to the R129, how would you compare what you offer with the official R129 DVD from M-B? All I know is that the word on WIS is that it is very, very clumsy to navigate through the menus, and the R129 DVD is superior in this regard.

One comment about the R129 DVD from M-B: the Diagnostic Manual for the '90-'93 power top system is for the W124 cabriolet! This is a big mistake, and maybe it has been subsequently corrected in a revision to the DVD. If you get a DVD and it is not, let me know, and I can get the correct Diagnostic Manual to you.
