- Ask specifically about Ringland failure — verify it has been addressed
- Verify all open recalls at NHTSA.gov/recalls using the VIN
- Have an independent mechanic perform a pre-purchase inspection ($100–$200)
- Ask for service records — consistent maintenance history is the best reliability indicator
