Best Car Inspection Tools for Used Cars in Australia
Looking for the best tools for a used car inspection? As a professional vehicle inspector, I use the same tools when carrying out mobile pre-purchase car inspections on used cars throughout Australia to uncover accident damage, engine faults, worn tyres and hidden problems before they cost buyers thousands.
Whether you’re buying a used car, doing your own inspection, or diagnosing issues at home, this guide covers the essential tools that actually find problems – not just look good in your toolbox.
In Queensland, vehicles must meet strict safety standards, including a valid safety certificate when sold. You can review the official roadworthy requirements in Queensland before buying.
In Australia, both dealers and private sellers must meet legal obligations when selling used cars. The ACCC’s buying a used car advice helps you understand your rights and avoid costly mistakes.

What Tools Do Professional Pre-Purchase Inspectors Use?
As a professional vehicle inspector, these are the same tools I use when carrying out pre-purchase inspections on used cars throughout Australia. They help uncover hidden accident damage, engine faults, worn tyres and expensive repair issues before money changes hands.
Before inspecting any used car, I recommend carrying at least an OBD2 scanner, a tyre tread depth gauge and a paint thickness gauge.
