Questions to ask the seller before buying a 2021 Renault Trafic

- Have all the recalls been done? Can a Renault dealer confirm from the VIN?
- Can I see the service history and receipts for any big jobs?
What to check on a 2021 car
- MOT history
Check the reg below: its MOT history shows what has been failed or advised, and whether the mileage adds up.
- Service history
Look for regular servicing and receipts for big jobs like a cambelt or clutch.
- Finance and write-offs
MOT records don’t show outstanding finance or insurance write-offs. A history check does.
- Test drive
Listen for knocks over bumps, check every warning light goes out, and make sure the gears and brakes feel right.
