Walk around the car and kick the tires. While you are at it, smell for any sign of hot brakes, and see if the engine overheats once the fan and water pump are turned off. A Mechanic's Opinion Do not take the seller's word that any problems you may notice are minor, or that everything is fine. Whether you are buying from a dealer or a private seller, have the car checked out by a trusted mechanic at a regular repair shop. There may be a small charge for this service, but it can save you some major headaches and expenses later, especially if you are buying from a private seller, who has no automatic warranty repair responsibility.
Some garages have computer equipment that can help to diagnose the mechanical condition of the car.
Finding out about any mechanical or structural problems may influence how much you are willing to pay for the car or whether you want to buy it at all. Verify A Used Car's History Confirm the accuracy of the odometer reading and find out more about the car's condition and repair history by contacting the previous owner before you make the purchase. Massachusetts law requires a dealer to disclose to you the previous owner's name and address if you ask for this information. There are, however, some large loopholes in the law. New cars that were purchased in other states and returned under their lemon laws do not have to carry resale notices.
