Questions to ask the seller before buying a 2025 Mercedes-Benz CLA

Ask before you travel to see it. A seller who knows the car will have answers, and receipts.

1. Have all the recalls been done, especially the airbag and turbo oil line?
2. Can I see the service history and receipts for any big jobs?

What to check on a 2025 car

• Warranty left

  Ask for the date it was first registered and check how much of the maker’s warranty is left, and that it transfers to you. Electric and hybrid batteries usually have a longer, separate warranty.

• Servicing

  Servicing on time with the maker’s schedule keeps the warranty valid. Ask for the service book or the dealer’s digital record.

• Finance

  Nearly new cars are often still on finance. A history check shows outstanding finance, and whether it has been written off or stolen.

• Recalls

  Ask whether any recall work has been done, and check the reg on GOV.UK’s free recall checker.

• Logbook (V5C)

  The name and address should match the seller, and the VIN on the V5C should match the car.
