When I complained about the lack of repair information in the CD I puchased I was advised to buy the next version. This was a couple of months after I received my CD. I was told that this approach ro release updates is similar to any software development. So I guess we need to be patient because the E30 M3 repair technology is still be developed. Therefor if you require more advanced advise on the M3, perhaps you should wait for a couple of years or so until the 4th, or 5th release comes out. Just my opinion.
