Buying a used car without an inspection: What you risk

Jan 30 2026

Buying a used car without an inspection may seem convenient, but it exposes buyers to a range of potential problems. Many issues only become apparent after the vehicle is driven regularly or assessed professionally.

Across Australia including NSW, VIC, QLD, SA and WA, post-purchase repairs are a common issue for buyers who skip inspections.

Common Issues Found After Purchase

Some of the most frequent problems discovered after buying a used car without inspection include:

  • Undisclosed accident or flood damage
  • Engine or transmission faults
  • Brake and suspension wear potentially requiring immediate repair
  • Electrical issues and warning lights appearing shortly after purchase

Once the sale is complete, these issues are typically the buyer’s responsibility.

Why Test Drives Aren’t Enough

While a test drive can reveal obvious faults, it won’t uncover issues hidden within the engine bay, undercarriage, or past repairs. Many problems only appear during diagnostic testing or mechanical checks where possible for an inspector.

This is particularly relevant for private sales, where buyer protections may be limited.

Reducing Your Risk Before You Buy

One of the most effective ways to reduce risk is to have the vehicle independently inspected before purchase.

A pre-purchase car inspection can help identify issues early, giving you the confidence to negotiate, walk away, or proceed with clarity.
