What you should do: Listen for squeaks and rattles, and pay attention to any items that need to be repaired. A car that pulls to one side might be showing signs of previous damage. Paint overspray on the back of body panels and doorjambs can signal bodywork from a wreck. The smell of mildew or mold could indicate water damage, which you definitely want to avoid.
CR’s chief mechanic, John Ibbotson, says to avoid vehicles with signs of deep water exposure. “Even if a vehicle looks acceptable and may be working when you inspect it,” he says, “water damage could lead to many electrical problems down the road.”
Take at least 30 minutes for each test drive. If you are looking at multiple cars, drive them over different road surfaces on the same loop. Make sure to document everything in your phone’s notes app or on paper. A dealer may insist on sending someone along with you, and a private seller will certainly want to be present during your drive.
Be wary if a seller refuses to let you test-drive the car. While they may be trying to keep tire-kickers from wasting their time and adding miles to the car, they may also be trying to hide something from you. Take this as a sign to walk away and look at a different car.
