At least you can GET info on your car with the CD.
I'm sure there is a lot on the W124, but I already have a Haynes manual for that. Not the best, but I can get by with most repairs on that one.
The R129 (or any SL for that matter) has no such manual or CD anywhere! So every venture into that car is a research project! Or I look for M-Benz on the other forum since he stripped his down to the bone to do a conversion upgrade.
Not sure if anything is available for the ML, but I got a year left on the factory warranty so I'd better find out soon...
