it will be interesting to see what they put in the CD. All the previous CDs were a collection of print manuals. There never was such a thing for the 140 chassis. All the info systems I have in print are by systems not car type.
The MB tech site
www.startekinfo.com costs $20 a day. If one were industrious one could get most of the important info like wiring diagrams and system information during that time.
