How to Read a Vehicle Inspection Report: What Every Section Means and What's Missing If It Isn't There

You paid $329 for a report and you've been sent a 22-page PDF you don't fully understand. That's normal. This guide walks through every section of a professional pre-purchase inspection report — what should be there, what the terminology means, and what missing sections tell you about the inspector who did the job.

Section 1 — Vehicle identity

Every report should open with plate, VIN, engine number, odometer at inspection, fuel type, transmission and colour. This is your evidence that the inspector saw the same car you're buying.

• VIN should be sighted on both the compliance plate and the vehicle's stamped location (typically at the base of the windscreen or under the passenger seat).
• If VIN is only recorded from the compliance plate, that's a red flag — cloned cars have matching plates but mismatched stamped VINs.

Section 2 — Documentation review

The inspector should note whether they sighted service books, receipts, previous pink slips, and how far back service history extends. A well-serviced 8-year-old car should have 6+ documented services. Two stamps means either lost history or genuinely thin history — either way, negotiate on it.

Section 3 — Exterior and structural

Look for paint depth gauge readings. Factory paint on Japanese and Korean cars typically reads 90–160 microns. Repairs usually read 200–400+. A single panel over 200 microns is not automatically bad — the report should tell you which panel, how much, and whether the paint blend suggests a minor bumper scrape or a full structural repair.

• "Consistent gauge readings" = factory paint, no evidence of accident.
• "Elevated readings on right-hand panels" = right-side impact history, minor to moderate.
• "Weld seams visible in boot floor / firewall / A-pillar" = structural repair. Walk away or negotiate hard — resale hit is 25–40%.

Section 4 — Mechanical (engine, transmission, drivetrain)

This section should be organised by system — engine, cooling, transmission, drivetrain, brakes, suspension, exhaust, steering — with a pass / advisory / fail marker against each. "Advisory" means it works today but will need attention within the next service or two. "Fail" means it's a defect the buyer needs priced now.

Section 5 — OBD-II diagnostic scan

If the report doesn't have this section on a car built after 2001, the inspection is incomplete. Full stop. This is a five-minute check with a $200 scan tool. The report should list:

• Current fault codes (present at time of scan).
• Stored / historical fault codes (been cleared but re-appeared).
• Readiness monitors (whether the emissions systems have completed their self-tests — a car that fails multiple readiness monitors was recently reset, often to hide a check-engine light before sale).
• Freeze-frame data on any stored code (RPM, coolant temp, load — tells you when the fault happened).
• Where available: engine runtime hours, total fuel consumed, distance since last DTC clear.

Section 6 — Road test findings

The report should specify route length, conditions (freeway included?), and any drivability observations: cold start behaviour, transmission shift quality, noises under load, brake feel, steering pull, suspension noises. A single line saying "road test completed satisfactorily" is not a road test report — it's a signature at the bottom of a page.

Section 7 — Photos and video

A modern PPI should include at minimum 25–40 photos: every panel corner, VIN plate, engine bay top-down, underbody, tyre tread with wear indicator visible, dashboard cluster with lights and odometer, and every defect close-up. Short videos on any moving or audible defect (transmission flare, exhaust smoke, suspension knock) turn ambiguous descriptions into evidence.

Section 8 — Cost estimates (Elite only)

The most negotiation-effective part of any report. Every defect should have three columns: repair scope, estimated Sydney parts cost, estimated Sydney labour cost. This is what you use to walk into the seller with a specific dollar figure and evidence to back it up.

What's suspicious if it's missing

• No OBD-II output on a modern car → inspection incomplete.
• No paint gauge readings → structural coverage guessed.
• No underbody photos → underbody not properly inspected.
• No PPSR search included → basic due diligence skipped.
• No verbal debrief offered → you can't ask follow-up questions when confused.

How to use the report

1. 1.Read it end to end before contacting the seller.
2. 2.Highlight every "advisory" and "fail" line.
3. 3.Add up estimated repair costs on the Elite report (or ask us for figures if you have Comprehensive).
4. 4.Contact the seller with a specific dollar figure and a copy of the report link — sellers are far more likely to negotiate when handed itemised evidence rather than a general request for a discount.
5. 5.Save the shareable report URL — you can send it to your mechanic, insurer, or future buyer.

Common questions

How long is a report valid for?

The report describes the car on the day of inspection. If the seller drives it another 2,000 km before you buy, minor changes are possible. Most buyers act within 3–5 days of the report and that's a safe window.

Can I share the report with the seller?

Yes — that's how negotiation happens. Our reports are shareable by link so you don't need to email a PDF.

What if my mechanic disagrees with a finding?

Send them the report link and ask them to note the disagreement. We're happy to jump on a three-way call with your mechanic and our inspector to reconcile — no charge.
