Questions to ask the seller
Questions worth asking any seller before you hand over money:
- 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)?
- How many owners has it had, do you have the maintenance records, and why are you selling it?
- Are you open to me having an independent mechanic inspect it before we settle on a price?
