Quick Answer: Used Car Inspection Checklist (2025)

Stage	What to check	Red flags
Paperwork	Service history, VIN, PPSR	Money owing, write-off, mismatched VIN
Exterior	Rust, paint, tyres	Fresh overspray, uneven gaps, bald tyres
Interior	Water damage, electronics, A/C	Musty smell, warning lights
Engine bay	Leaks, fluids, belts	Milky oil, coolant issues, oil leaks
Test drive	Brakes, steering, transmission	Vibrations, slipping, clunks

If you want the “fast version”, do a PPSR check, then book an inspection — or contact us and we can organise it.

Brisbane & SEQ quick take

Brisbane and SEQ have a few extra inspection gotchas: flood/water damage (check carpets and silt), coastal corrosion (Gold Coast/Sunshine Coast), and stop‑start wear. If you want a second opinion, talk to our team — we can shortlist safer options and organise inspections.

Extra SEQ checks worth doing:

• Lift floor mats and check underlay for water lines/silt.
• Check the boot spare wheel well for moisture.
• Scan roof/bonnet for hail dings in angled light.
• Test A/C properly (it should get cold fast in Queensland heat).
• Look underneath for coastal surface rust (especially near the Gold Coast/Sunshine Coast).
• Bring a torch and paper towel so you can spot fresh leaks and grime in low light.
• Take a quick photo of the VIN plate so you can cross-check it later.

Red Flags: Walk Away If...

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.

Frequently Asked Questions About Used Car Inspections

How long does it take to inspect a used car?

A thorough used car inspection takes 30-60 minutes. Don't rush it—taking your time can save you thousands in repair costs. Our checklist covers exterior, interior, engine bay, and a comprehensive test drive.

What should I look for when inspecting a used car?

The most important things to check are: signs of accident damage (mismatched paint, uneven panel gaps), rust (especially wheel arches and underbody), fluid leaks, tyre condition, and how the car drives during the test drive. Always check the service history and run a PPSR check.

Should I pay for a professional pre-purchase inspection?

Yes, if you're spending over $10,000 or aren't confident inspecting cars yourself. A professional inspection costs $150-$300 but can reveal hidden problems that would cost thousands to fix. It's cheap insurance.

What are red flags when buying a used car?

Walk away if: the seller won't allow an independent inspection, service history is missing, PPSR shows money owing or write-off status, VIN doesn't match paperwork, there are water stains in carpet (flood damage), or the price seems too good to be true.

How do I check if a used car has been in an accident?

Look for: mismatched paint colours between panels, uneven panel gaps, overspray on rubber seals, different bolt colours in the engine bay (indicating part replacement), and VIN plates that look newer than the car. A professional inspection can also detect hidden frame damage.

What questions should I ask when inspecting a used car?

Ask the seller: Why are you selling? How long have you owned it? Is there a service history? Any known issues? Has it been in any accidents? Has the odometer been replaced? Can I take it for an independent inspection?
