Questions to ask the seller before buying a Mazda 2

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

  1. Does it get regular motorway runs?
  2. Any recent work on the rigid brake pipes? (Flagged at MOT 6.2× as often on the Mazda 2 as on other cars the same age.)
  3. Any recent work on the ball joint? (Flagged at MOT 3.4× as often on the Mazda 2 as on other cars the same age.)
  4. Any recent work on the headlights? (Flagged at MOT 3.3× as often on the Mazda 2 as on other cars the same age.)
  5. Can I see the service history and receipts for any big jobs?
