Hello,
I have subscribed on the EPC run by Snap-On for Mercedes-Benz for about 8 years;
http://service-parts.mercedes-benz.com/dcagportal/DCAGPortal/portal.action
18 Euro per year for the EPC only and it works very well. The downside is that it's run on JAVA which is a real PITA to keep up with their continous updating. JAVA is more or less out here in Norway, too much hassle, even the bank systems has finally stopped using them. And the situation for me here at work is that I have max. 5-10 minutes to use the EPC until it is shut down, simply due to that JAVA thing. I'm not sure JAVA runs on Mac/Apple either.
I am not so good at data, but I take screenshots of the EPC and paste into PowerPoint, there I modify and create the image I want and save it as png-files for best quality.
