Star Diagnostic c4 for 211 and trucks

[ealltech]

First of all,i'm sorry if there are other threads that discuss my matter,but i couldn't find anything that could really help me.

So,my father wants to get a MB Star c4 diagnostic program,that comes with an IBM pc.We have a w211 '07 facelift,but we will also need the diagnostic for trucks that we repair.Is it compatible for both?The estimated price given to him is 2-2.5k euros.Are there any instructions given with the program ?Also,what are the main differences between the real MB program and the "broken" ones ?

I can really use some sites that sell these kinds of programs,so i can compare the prices.If there are also some discussions on this topic in the forum,too,feel free to link them to me,i couldnt find anything on my own..

If there is anything more you think i should know,feel free to enlight me ^_^
