What do you guys do for service manuals on your cars? I just purchased the 2 dvd Mercedes WIS ASRA program and found it almost useless. Has anyone bought this before? It has over 8 gigs of repair info that is very hard to use. Not only that, but it is rediculous to install on your pc. I contacted our local dealership and they did not have manuals-certainly not everyone brings these to the dealership to be serviced. What do the techs use in the shop? This stinks!!
