• All warning lights off?

After drive:

• Check under car for fresh leaks
• Feel brake rotors for excessive heat

Red Flags: Walk Away If...

• Seller won't let you do an independent inspection
• Service history is missing or incomplete
• PPSR shows money owing or write-off
• VIN doesn't match paperwork
• Seller is evasive or pushy
• Price seems too good to be true
• Water stains in carpet or boot
• Mismatched panels or paint
• Unusual engine noises

When to Get a Professional Inspection

Even with this checklist, we recommend a pre-purchase inspection from a qualified mechanic if:

• You're spending over $10,000
• The car has high kilometres
• You're buying interstate
• It's your first car purchase
• You're not confident inspecting yourself

Cost is typically $150-$300—cheap insurance against a $5,000 repair bill.
