How not to get scammed on Craigslist as a buyer would be simple from this question. You can get sufficient information from the seller by asking the exact reason for selling the car. The reason could be that they want to upgrade their car, they could be looking for a big SUV for the family, or sometimes sellers are interested in buying new cars. However, if the seller gets tense with this question or hesitates to answer, be alert, as there might be some issues with the car.
