The DIY Used Car Inspection Checklist (Built From 1,000+ NSW Inspections)

Tick this off on your phone as you read, then print it for the viewing. It catches the obvious bad cars before you pay anyone for a professional inspection. It will not catch the expensive hidden stuff, and we are honest about that below.

What this checklist will and will not catch

A 20-minute walkaround rules out the worst cars: obvious crash repairs, bald tyres, warning lights, a service book that does not exist. What it cannot do is see inside the engine or read the history of fault codes. Use it to filter, not to give a car the all-clear. If a car passes this list and you are serious about it, that is exactly when a professional inspection pays for itself.

Before you leave home

The 40-point walkaround (in order)

Exterior; panels, paint, gaps

Tyres and wheels

Glass, lights, and trim

Under the bonnet

Interior; seats, controls, electronics

Boot, spare, and tools

Under the car (what you can see without a hoist)

Paperwork

The test drive; 12 things to check

After the test drive

Park, leave the engine running for a minute, then check under the car again for fresh drips. Look back at where it was parked for puddles. Re-read the dash for any lights that came on warm. Note anything that failed; that is your negotiation list or your reason to book a professional inspection before paying.

When to walk away (and when to call us)

Walk away now if

The seller will not show service records, the VIN or seller name does not match the papers, there are signs of a structural repair, the odometer disagrees with the wear, or the seller is rushing you to pay today. None of these are worth the risk.

The car passes this list and you are ready to buy. That is the point where a hoist, a scanner, and a paint gauge tell you what the walkaround cannot. Get a quote across Sydney, it is the cheapest insurance in the process.

Print the checklist

Use the Print button at the top to print this checklist or save it as a PDF, then take it to the viewing. If anything on it fails, the next step is a professional inspection at the seller's location.

Frequently asked questions

Will a DIY checklist replace a professional inspection?

No. A walkaround rules out the obvious bad cars before you pay anyone, but it cannot see cylinder wear, fault-code history, or paint depth. It narrows the field; a mechanical inspection confirms the car.

What should I bring to a used car viewing?

This checklist, a torch, a phone for photos, a magnet wrapped in cloth for filler, and a tyre tread gauge if you have one. View in daylight and never in the rain, which hides paint defects.

How long should a DIY walkaround take?

About 20 to 30 minutes plus a test drive. If the seller is rushing you, that itself is a warning sign worth noting.

Can I do this checklist on a dealer car?

Yes. The same checklist works on dealer stock. A reputable NSW dealer will give you time and access; one who will not is telling you something.

Service Area

We Cover Western Sydney

We refer across Western Sydney and the surrounding areas. Our local mechanics come to the vehicle, wherever it is.

How It Works

How It Works, Start to Finish

Our local mechanic inspects the car and keeps you informed at every step - whether you come along or leave it to them.

Two ways to inspect

You meet the mechanic there

Turn up at the car, watch the checks first-hand and ask questions on the spot. Tell us in your request that you want to attend and the mechanic will work around you when they agree a time.

They inspect on your behalf

Can't be there? The mechanic carries out the full inspection for you, then calls you with the findings once they have finished. You never have to take the seller's word for it.

From booking to results

1

Tell us about the car. The make, year and the suburb it is in, plus anything you are worried about.

2

We alert local mechanics. Your details go to our local mechanics who cover that council.

3

They call you. The mechanic quotes their price and agrees a time window with you directly.

4

On the day. They ring the seller about 20 minutes before arriving, then inspect the car on site.

5

Get the results. A clear verbal summary, plus a written report if you asked for the Comprehensive Inspection.

What if the vendor doesn't pick up?

It rarely happens - most inspections run exactly to plan. But if we can't reach your nominated contact, we don't simply leave. The mechanic makes three touchpoints across about 35 minutes: a call around 20 minutes before arrival, a call and text on arrival, and one more call after waiting 15 minutes. If there is still no answer, the mechanic rings you personally to agree the next steps - your booking is never wasted.

Standard & urgent inspections

Most are arranged a few days ahead, inside 8am to 8pm. Need it sooner, or outside those hours? Say so in your request and we will flag it to the mechanics.

Every mechanic is checked

We verify ABN and licence before a local mechanic joins the network, and we only refer independents with no dealer ties.

Cars only

Sedans, hatchbacks, wagons, SUVs, 4WDs, AWDs, utes, vans, people movers, coupes and convertibles. Not motorbikes or trucks.

Classic, luxury & exotic cars

These take longer and need extra expertise, so we match them with one of our local mechanics who knows the marque. Expect the quote to reflect that. As a guide:

  • Classic - generally 30 years or older, or a recognised collectible.
  • Luxury - premium marques such as higher-end Mercedes-Benz, BMW, Audi, Lexus, Land Rover, Jaguar or Porsche.
  • Exotic - supercars and rare high-performance models such as Ferrari, Lamborghini, McLaren, Maserati, Aston Martin or Bentley.

Not sure which applies to your car? Put the make, model and year in your request and the mechanic will confirm everything in their quote - no surprises.

Minimise the risk of buying a second-hand vehicle

A used car is one of the biggest purchases you'll make, and the seller isn't on your side. An independent mechanic going over the car, and a plain-language walk-through of what they found, put the facts in your hands before you sign anything or hand over a deposit.
