Before You Buy a Used Mercedes-Benz GLS

  • Ask the seller for the registration number, then check the MOT history for failures, advisories and recorded mileage — it is free on GOV.UK.
  • 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.
