As someone who's been tinkering with cars for years, I was excited to dive into this book. The theory sections on auto systems operation are genuinely solid - it breaks down complex concepts in a way that makes sense, especially if you're prepping for ASE tests. I found myself nodding along during the engine and transmission chapters.

But man, the inconsistencies drove me nuts! There's this one diagram showing suspension components with numbered parts... and no key to tell you what's what. It's like getting a puzzle with half the pieces missing. And don't get me started on Chapter 10 - blank graphs where sensor waveforms should be? That's like a cooking show forgetting to show you the finished dish.

The physical book feels a bit cheap too - pages arrived with smudged ink, and I spotted several typos that made me double-check if I was reading correctly. At this price point, I expected better quality control.

Would I recommend it? If you can overlook the flaws and just need theory basics, maybe. But for actual diagnostic work? You're better off combining free YouTube tutorials with manufacturer service manuals until they release a properly edited version.
