Red flags to slow down for
No VIN shared
A seller who will not share the VIN makes it harder to verify basic details before you spend time or money.
Title story changes
Different explanations about ownership, liens, salvage status, or registration deserve extra review.
Pressure for deposit
Urgency can be real, but it is also common in risky private-sale situations. Decide your walk-away rules first.
Mileage feels inconsistent
Compare mileage against photos, service records, age, wear, and seller answers.
Inspection refused
A seller can choose not to allow inspection, but you can also choose not to buy without one.
Too-good price
A price far below comparable listings should trigger more questions, not faster payment.
What to do next
Ask for the VIN, title status, maintenance records, seller ID/name match, and whether a mechanic can inspect the car. Keep the conversation in writing when possible.
Use online checks as a screening step. They do not replace a mechanic, DMV/title review, lender lien check, or legal advice.
Optional screening tool
VIN Checkup can help you review vehicle information before you decide whether the car is worth deeper inspection.
