This book gets the bottom line done. I mean the conversion charts are good, and the information is all pretty much there, but I really had a hard time understanding some of the instructions. And they really should have done a better job editing. The myriad of typo's made it that much more difficult. But, that being said, the directions can get you through most minor repairs.
I got mine for 12 bucks at an auto parts store. That's about what it is worth to me.
