well after waiting for some opinions i bought a day's worth of access. i can honestly say burning 20 dollars would have been more helpful. the site is pretty bad if you are searching for things like torque specs, pics of individual parts, and instructions on repair. you get overloaded with every little MB tech bulletin ever posted and sifting thru all that stuff will take a while. i'm a little perplexed at the poor site and lack of technical information. i've worked on other luxury vehicles in the past and didn't expect this sort of trouble for my entry level MB.
