A clean photo, friendly seller, and smooth test drive are useful signals, but they do not tell the full story. Before paying a deposit, run the VIN and compare the report with the seller's documents.
Look for title problems, accident records, mileage inconsistencies, open recalls, number of previous owners, and whether the vehicle was used in fleets, rentals, or auctions. These details can change the price you should offer or help you walk away.
A report is not a replacement for a mechanic inspection. It is a fast filter: use it first, then inspect the car, verify service records, and confirm the VIN on the dashboard, door frame, and paperwork.
