" Know your route. If you are taking someone out for a test drive, used car sale site Auto Trader suggests making sure a friend or family member not in the car know the planned route, estimated return time and your cellphone number.
Keep buyers in sight. If a buyer arrives with an entourage, do not let the people separate, advises safety site iLookBothWays. Scam artists like to split up, with one engaging the seller with questions and the other asking to use the washroom. Once inside the house, the person can perpetrate a theft.
Handling payment
Visit a bank. If you are accepting cash, do so in your bank so you can deposit the money right away. If you take a cheque, verify it with the bank that issued the cheque, not your bank.
Wait to transfer ownership. Before transferring vehicle ownership to a buyer, make sure you have received the full agreed-upon payment, warns Auto Trader.

"If you have an inkling there's something wrong, just stop and contact your local police services," he said, adding it is "not at all" a bother to police who are happy to offer some friendly advice over the phone"
