Choosing a training manual for automotive powersports repair usually starts with a question: should you buy a broad service textbook that covers the entire repair process, or a specialized engine-repair course from an OEM? Condition makes the decision harder, because used training materials range from clean reference copies to worn shop documents. The four options here represent different approaches: two comprehensive hardcovers of the same Tim Gilles textbook and two engine-repair-specific binders from GM and Ford.
Quick Take
If you need one comprehensive, clean reference, the hardcover Automotive Service: Inspection, Maintenance, Repair is the choice that removes condition as a concern. If you are buying on a tight budget, the Mindtap Course List version of the same book gives you the same core coverage for the lowest price in this group. For mechanics who want focused OEM training, the GM STG folder and the Ford STST binder are the specialized alternatives.

Product Notes
GM STG Folder - Engine Repair Course

The GM STG folder is a used training binder from General Motors' Service Technology Group, focused specifically on engine repair. Its USD 26.95 price makes it an inexpensive entry point if you want a dedicated, single-subject course rather than a broad service manual. Because it is used, you should expect wear such as stains, writing, rips, or water damage; it is not a clean reference copy. Choose it if you are comfortable with a working shop document and want the engine-repair focus at a low price.
Ford STST Engine Repair Reference Binder

This Ford technical training binder stands out for its content and format: it is ringbound, illustrated, and compiled by Ford Motor Company's Parts & Service Division for vocational and adult education. At USD 34.99, it costs more than the GM folder but still less than the comprehensive hardcovers. The included supplements cover superchargers, engine cooling, lubrication, fastening and torquing, and basic gasoline engine theory. The trade-off is physical condition: the exterior is heavily soiled and scuffed, and there is a handwritten name inside, though the rings are tight and the text pages are clean.
Automotive Service: Inspection, Maintenance, Repair (MindTap Course List)

This is the like-new hardcover of Tim Gilles' comprehensive service textbook, priced at USD 64.99. The copy has a firm, clean page block, unblemished binding, and straight boards with no markings. If you want a single durable reference that covers inspection, maintenance, and repair for a full range of automotive work, this copy gives you the least amount of condition uncertainty in the group. The obvious limitation is price: it is the most expensive option here, and the same ISBN is available for much less in a very good condition copy.
Mindtap Course List Ser.: Automotive Service

The budget pick in this comparison is the Mindtap Course List hardcover of the same Tim Gilles textbook, listed at USD 23.90. It is marked Very Good and carries the Revised feature, so you get the same 1,632-page coverage of automotive technology and repair at a lower price than the clean hardcover. The reason to choose it is straightforward: you want the comprehensive textbook on a tight budget. The limitation is condition grading: Very Good means you should expect some prior use, unlike the cleaner copy.
Final Recommendation by Use Case
- For a single clean comprehensive reference, pick the hardcover Automotive Service: Inspection, Maintenance, Repair.
- If you want the same broad textbook without the top price, go with the Mindtap Course List Ser.: Automotive Service.
- For focused engine-repair training, the GM STG folder is the budget OEM option, while the Ford STST binder gives you illustrated supplements and a Ford perspective.
