Thanks to all for the reply.
I'll appreciate the suggested information. As far Sorbo's question, as per my experience (always manual), MB manual, probably as already known, is really not the best. My reference are my previous BMW (E36 318 and E34 M5), both two was more "precise" in the shifting, less obstination in fast shifting. Also the shifting sound into the cabin was less respect mine W202, in which you can well hear the "clonk" feature.

I'm really happy with my W202, this is a little downside, as per my opinion.

Other think that I'd like to have as previous BMW is a mechanical LSD but, this is an old story for both MB and BMW, which are, by now, all provided with ESP, ASR,....

ciao
