When you're building your reference collection for automotive powersports repair, one of the first choices you'll face is whether to start with a broad service and maintenance guide or go straight into a focused engine performance manual. Both approaches are valuable, but they serve different needs and budgets. The two textbooks here have you covered, but in very different ways.
Quick verdict: Choose Tim Gilles' *Automotive Service Third Edition* if you want a hardcover, brand new guide that covers inspection, maintenance, and repair at a lower price. Choose Ken Pickerill's *Automotive Engine Performance (7th Edition)* if you need a comprehensive, shop-oriented engine performance reference and don't mind paying more for a larger trade paperback.

Where Each Textbook Wins
Automotive Service Third Edition by Tim Gilles wins on price, condition, and all-around scope. It's a revised hardcover that includes a resource CD, making it a self-contained learning kit for someone new to the field. The "Inspection Maintenance Repair" title tells you it's meant to be a general service companion, not a single-topic deep dive.
Automotive Engine Performance (7th Edition) by Ken Pickerill wins on specialization and page count. At 1,184 pages, this trade paperback is built for classroom and shop use, with a focused lens on engine performance. If your work or studies revolve around diagnostics and engine systems, this is the deeper resource.
Product Notes
Automotive Service Third Edition by Tim Gilles
Tim Gilles' textbook is a solid entry point for anyone entering automotive powersports repair. The hardcover format is durable for a shelf reference, and the included resource CD adds extra material for self-study. Published by Cengage Learning, it's a revised edition, so the content has been updated from earlier versions. The condition is brand new, which is nice if you want a pristine copy for your own notes or a student's hands. At $42.49, it's the more affordable option here. The drawback is that its strength is breadth, not depth. If you already know engine systems and only need performance-specific details, this broad guide will leave you wanting more. It's best as a general introduction or a quick refresher across inspection, maintenance, and repair.
Automotive Engine Performance (7th Edition) by Ken Pickerill
Ken Pickerill's book goes all-in on engine performance, a critical slice of automotive powersports repair. With 1,184 pages, it offers substantial depth, and the trade paperback format is lighter than a hardcover, which can be handy for carrying between classroom and shop. It's described as like new, so you're getting a clean copy without paying full new price. The 7th edition is revised, keeping it current for its topic. At $70, it's the higher-priced pick, but you're paying for specialization and volume. The limitation is that it's an engine performance text, not a general service manual, so you'll likely need a separate book for brakes, steering, suspension, and other maintenance tasks. If you're an aspiring technician with a focused interest in how engines run, this is your better match.
Final Choice by Use Case
If your automotive powersports repair learning is just beginning or you want a single affordable volume that touches on inspections, maintenance, and repairs, go with Tim Gilles' *Automotive Service Third Edition*. If you're already comfortable with basic service and need to level up your engine performance knowledge for classroom or shop work, Ken Pickerill's *Automotive Engine Performance (7th Edition)* is worth the extra money. Let your current skill level and budget steer the decision.
