Questions to ask the seller

Questions worth asking the seller of this Ford before you buy, drawn from its public record:

  1. Owners of this model report fuel system, diesel problems more than anything else. Has this car shown any fuel system, diesel symptoms, and are there repair records for it?
  2. Owners of this model report engine problems more than anything else (owners tend to report it near 15k miles). Has this car shown any engine symptoms, and are there repair records for it?
  3. Has this car been in any accident or had any structural, airbag, or flood-related repair? Do you have a clean title and a recent history report (Carfax / AutoCheck)?
  4. How many owners has it had, do you have the maintenance records, and why are you selling it?
  5. Are you open to me having an independent mechanic inspect it before we settle on a price?

The fine print: this verdict is computed from public NHTSA complaint and recall records for the 2021 Ford F-350 Supercab as a model, not for any individual car. A well-maintained example of an “Avoid” can outlast a neglected “Buy”. Informational only, so always get a professional pre-purchase inspection.
