- Make sure the V5C logbook matches the seller and the vehicle, and ask for the service history.
- With the registration, run a vehicle history check (such as HPI) for outstanding finance, write-offs and theft.
- Test drive it, and ask the seller about any warranty — it is between you and them, not Autoza.
