What we sell

Illustrated study material on how cars work, for automotive students, new technicians and car owners, delivered as downloadable PDF files. Nothing is shipped physically.

This is study material, not a course. It does not give credit, hours or a certification. It is not affiliated with or endorsed by ASE. ASE is a registered trademark of the National Institute for Automotive Service Excellence. The practice questions were written for this material.

Your purchase

One payment. There is no subscription and no recurring charge.
Payment is processed by Stripe. We never see or store your card number.
The download link is emailed to the address you enter at checkout, normally within a few minutes.
If a title is sold before it is finished, you receive it in the same folder as soon as it is ready, at no extra cost.

What you may and may not do with the files

You may read the files on your own devices and print them as often as you want for your own use. You may not resell them, share them publicly, upload them to file-sharing sites or distribute them to third parties.

Refunds

See the refund policy.

Liability

We take care that the content is accurate. Even so, the material is educational: your owner's manual, the manufacturer's service information, your instructor and your shop's procedures always come first. Never work under a car held up only by a jack, let the engine cool before you open the cooling system, and leave brake, steering and high-voltage work to trained technicians unless you are one. To the extent allowed by law, our liability is limited to what you paid.

Changes and governing law

We may update these terms; the date at the top shows when. These terms are governed by the laws of the State of Florida, United States.
