Questions to ask the seller
Questions worth asking the seller of this Mercedes-benz before you buy, drawn from its public record:
- Owners of this model report engine problems more than anything else (owners tend to report it near 17k miles). Has this car shown any engine symptoms, and are there repair records for it?
- 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?
