Common questions

Everything you need to know before you order

What exactly do I get?

PDF files, sent the moment you pay. Volume I is 59 pages, Volume II is 54 and Volume III is 55. The bundle gives you all three, 168 pages in all.

Is this a summary of the videos?

No. The videos tell you what to watch out for. The books are the reference layer: tables, checklists, worksheets, wiring diagrams and calendars to print and use at the counter or in the garage.

Will the specs fit my car?

The books give typical ranges and tell you exactly where to find the figure for your own car. Where a spec varies by engine or year, they say so instead of guessing.

Can I buy Volume III on its own?

No. The Buyer's Reliability Blueprint only comes with the complete bundle, along with the cross-reference index and the combined annual calendar.

Do I need tools or experience?

No. Most checklists need only your eyes, a flashlight and a phone camera. Where a job needs a professional, the books say so.

What if it is not for me?

Seven days, money back, no questions. Write to [email protected] and we sort it.
