About the Author

David MacMillan

David MacMillan is not a car dealer, mechanic, or financial guru. He is a U.S. Army veteran, husband, father of twelve (grandfather of many more!), and longtime follower of debt-freedom principles. Over thirty years and roughly thirty vehicles, he developed a practical method for finding trustworthy private sellers, avoiding costly mistakes, and buying with confidence — out of pure necessity. This book is the result.

The Method in Brief
  • Read the seller before the car
  • Let the advertisement confess
  • Earn the trip before you spend the gas
  • Inspect what you can, outsource what you can't

It taught me everything.

The Rules I Broke

I knew better. My wife told me something was wrong. There were seven red flags before I handed over the cash. The 2007 Honda Odyssey became the best example I have of knowing the method and ignoring it anyway. Cardboard on the garage floor for months.

Have an Exit Before You Enter — Know the resale, know the repair reserve, know your ceiling.

Inspect What You Can, Outsource What You Cannot — You don't need to be a mechanic. You need to be willing to look.
