Buying a Used Car on Facebook Marketplace or Craigslist: The Complete Pre-Purchase Checklist
Private-party marketplaces offer $2,500 to $4,500 in savings compared to franchise dealerships, but every private sale is legally "As-Is." Following a structured pre-screening and on-site inspection workflow protects you from curbstoners and hidden mechanical money pits.
Key Takeaways for Used Car Buyers
- Always verify that the seller’s photo ID matches the printed name on the front of the paper title before paying for anything—never buy an "open" or unsigned title from a flipper.
- Use a $29 Remote VIN & Listing Red-Flag Audit to screen 2–3 listings for recalls, check-digit authenticity, and model-year powertrain defects before scheduling an on-site visit.
- Insist on a dead-cold engine start so the mechanic can hear timing chain rattle, lifter tick, or piston slap that disappears once the engine is warmed up.
Step 1: Screen Out Curbstoners & Title-Skippers in 2 Minutes
Over 30% of "private seller" listings on Facebook Marketplace and Craigslist are actually posted by unlicensed flippers who buy salvage or auction cars with hidden transmission/overheating issues, wash them, and flip them without registering the title in their own name.
Ask three simple questions by message before meeting: (1) "Is the title clean and printed in your personal name with no lien?" (2) "Can you share the 17-digit VIN?" and (3) "Are you comfortable with my mobile mechanic doing a 60-minute pre-purchase inspection in your driveway?" Any seller who dodges those three questions just saved you a wasted trip.
Step 2: Check Tire DOT Date Codes, Not Just Tread Depth
Garage-kept or low-mileage cars often have plenty of tread depth on tires that are 7 to 9 years old. Rubber compounds oxidize and crack internally after 6 years, creating a highway blowout hazard. Check the last 4 digits of the DOT stamp on the sidewall (e.g., "4219" means the 42nd week of 2019). Four expired tires represent an immediate $700–$1,100 negotiation deduction.
