$500? Never mind.
Good advice, I'll check out the CDs. I mean the Haynes 123 diesel manual is better than nothing, but some things are different and the Haynes-es (plural) always have gaps.
Useful though. For my Beemer, I've got the Haynes and the Bentley. The Bentley has a lot of good in depth info that the Haynes doesn't but now and then, the Haynes will cover something the Bentley doesn't.
