What is a pre-purchase inspection?

An independent check of a used car before money changes hands, covering identity and paperwork, body and paint, engine and transmission, a road test, and the wear items that will need spending on soon.

How long does a pre-purchase inspection take?

A thorough one takes 60 to 90 minutes including a road test. Rushing it is how accident repair and imminent timing belt work get missed.

What are the biggest red flags?

Inconsistent paint depth across panels, mismatched VIN stampings, oil in the coolant, a slipping clutch or harsh automatic shifts, and a service history with gaps around expensive interval work.

Should the buyer be present?

Ideally yes. Walking the buyer around the car with a graded sheet and photos turns the inspection into advice they trust rather than a document they skim.

How to use it

Start with the paperwork

VIN, documents and service history first. If the identity does not check out, nothing else on the sheet matters.

Price the wear items

Tyres, brakes, battery and timing belt turn into a number. That number is what the buyer negotiates with.

Finish with a plain verdict

Buy, buy at a lower price, or walk away — plus the immediate spend. Buyers pay for the conclusion, not the list.
