I've bought one....
Think I've saved more than a few people good money on information
Learnt the hard way from spending money on bits & pieces
ABS pumps, pretty know all there is on them now - revisions, compatibility and wiring differences
door controllers, climatronic panel upgrades with info, radio upgrades - spent time doing pdf diagrams (now deleted)
Plus loads more useful info that & contacts that is probably useful.
Research, time, experiments... all costs money and headaches.... no matter, live and learn, live and learn!
