How to Use This Checklist

This checklist is designed to be printed and taken with you each time you view a used vehicle. Work through each section in order — exterior first, then interior, under the hood, tyres, and finally the test drive. Mark each item as you go so nothing gets overlooked in the moment.

Keep in mind this walk-around is your first filter. It helps you spot obvious problems and ask sharper questions. It does not replace a professional inspection. Once a car passes your own review, arranging a mechanic's check is a smart next step — see why a mechanic's inspection is worth the cost for what that process typically involves.

For a broader look at costs you should account for before making an offer, the used car cost checklist covers fees, insurance estimates, and other expenses beyond the sticker price.

Required

Printed copy of this checklist

Lets you mark off each item as you go without relying on memory or a phone screen.

Required

Tread depth gauge

Gives you an accurate tyre tread measurement rather than a visual estimate.

Required

Small flashlight or phone torch

Helps you examine the engine bay, underside, and interior corners in shadowed areas.

Required

Vehicle history report (e.g. from a licensed VIN check service)

Reveals recorded accidents, title issues, mileage discrepancies, and outstanding liens before you negotiate.

Optional

Magnet (small, wrapped in cloth)

Can help detect body filler used to hide rust or collision damage under paint, as filler won't attract a magnet.

The Inspection Checklist

Work through all five groups below, ideally in the order listed. If a seller pressures you to rush or won't allow a full inspection, treat that as a warning sign in itself. A trustworthy seller will give you the time you need.

Exterior

Inspect all body panels in daylight for dents, scratches, or uneven gaps between panels that may indicate past collision repairs. Must
Check paint colour consistency across all panels — mismatched shades or overspray near trim edges suggest repainting. Must
Look along the lower sills, wheel arches, and underside edges for rust, bubbling paint, or flaking metal. Must
Examine all glass for chips, cracks, or stress lines that could worsen or impair visibility. Should
Check that all lights — headlights, tail lights, indicators, and reverse lights — function correctly. Must

Interior

Sit in the driver's seat and check that the seat adjusts smoothly and all mirrors can be set correctly for your driving position. Must
Test every window, door lock, and electric control to confirm they operate without sticking or unusual noise. Should
Check the dashboard for any warning lights that remain on after the engine starts — note which ones and ask the seller. Must
Smell the interior carefully for signs of mildew, mould, or heavy air-freshener that may be masking a water leak. Must
Inspect seatbelts on all positions — they should latch, retract, and lock smoothly with no visible fraying. Must
Confirm the air conditioning and heater both reach their expected temperatures within a normal warm-up period. Should

Under the Hood

Check the engine oil on the dipstick — it should be between the min and max marks and appear amber or light brown, not black and gritty. Must
Inspect the coolant reservoir level and look for an oily film on top of the coolant, which can indicate a head gasket problem. Must
Look under the vehicle and around the engine bay for any fresh fluid puddles or staining on the ground. Must
Examine visible belts and hoses for cracking, fraying, or bulging — these are wear items that cost money to replace. Should
Check the battery terminals for heavy corrosion build-up, and note the battery manufacture date if a sticker is present. Nice to have

Tyres and Brakes

Check all four tyre tread depths using a tread depth gauge or the built-in wear indicators — worn tyres are a safety and cost concern. Must
Look for uneven tread wear patterns across a single tyre or between tyres, which can point to alignment or suspension problems. Must
Inspect tyre sidewalls for bulges, cuts, or cracking — any of these means the tyre needs replacing. Must
Confirm the spare tyre is present, in reasonable condition, and that the jack and wheel wrench are included. Should

Test Drive

Drive for at least 15–20 minutes and include a mix of city streets and a stretch of highway to assess performance at different speeds. Must
Brake firmly in a safe, clear area to check the car stops straight without pulling to one side or producing a grinding sound. Must
Listen for any knocking, rattling, or whining from the engine, steering, or suspension — note exactly when these sounds occur. Must
Test the steering by driving slowly on a level surface with hands lightly on the wheel — the car should track straight without drifting. Should
Re-check the dashboard after the drive for warning lights that may only appear once the engine is warm. Must
Note any unusual smells during or after the drive — burning rubber, hot oil, or exhaust fumes inside the cabin are all red flags. Must

Never Skip the Vehicle History Report

A seller may be honest, but they may not know their car's full history. Always run a VIN (Vehicle Identification Number) check through a licensed provider before or during your visit. The VIN is typically found on the dashboard near the windshield on the driver's side. A history report can surface undisclosed accidents, flood damage, odometer rollbacks, or an open lien — any of which could make a car a poor purchase regardless of how it looks in person.

For common warning signs and key questions to ask the seller, the practical inspection reference guide is a useful companion to this checklist. And if you want to understand how to act on what a professional mechanic's report tells you, how to use a pre-purchase inspection to protect yourself walks through that process step by step.

Avoid Viewing Cars in Poor Conditions

Never inspect a car at night, in heavy rain, or in a dimly lit garage. Poor lighting hides rust, paint mismatches, and fluid leaks that would be obvious in daylight. If a seller can only meet in these conditions, consider rescheduling. As noted in the pre-viewing preparation guide, arranging a daytime meeting in a well-lit location is one of the simplest ways to protect yourself.

A Rushed Seller Is a Red Flag

If you feel pressured to skip steps, make a quick decision, or skip the test drive, slow down. A legitimate private seller or dealer will allow you reasonable time to complete a thorough inspection. Feeling hurried is one of the most common conditions that lead to costly mistakes for buyers.

Avoid the common oversights that catch buyers off guard later — inspection mistakes that cost buyers later covers the most frequent slip-ups, from viewing in poor light to skipping the paperwork check.
