How to Detect Hidden Defects in a Used Car

by Edon Canada

Imagine yourself in the seller's shoes. You are trying to sell your old coupe for a bigger sedan. You gather the keys, rummage through your pile of junk for the owner's manual and old service records. You clean the engines, vacuum the interiors, rub out the stains on the cushions and put your coupe through a car wash.

When you get home to admire the sheen of the freshly polished wax, you notice some scratches and dents. Luckily, you have the cosmetics for such a contingency. And if your luck holds out, buyers wouldn’t even notice the dents and scratches. You are now ready to meet the buyers with a smile borne out of a clean conscience.

Imagine and remember this because this is exactly how a private seller with an ounce of business sense would prep his or her vehicle before a sale. Dealers could do it a lot better when they try. So, how do you see past the haphazard paint job? There is a way to detect hidden defects on the vehicle.

Body

• Check if the paint on the outside of the car matches the paint inside the door frame. Check for gritty surfaces and paint overspray on chrome – possible signs of a new paint job or masking body dents and scratches.
• Check if the panels line up evenly. Also check if there are any scuffs, scratches, dents or irregular protrusions in the wings and bumper – these could be warning signs of past accidents.
  

Doors and Trunk Lid

• Make sure that doors and lid open without any creaks and close smoothly without being slammed. A door or lid that doesn’t fit evenly could indicate that the vehicle was involved in a collision or was regularly driven in rough roads.
• Check that the locks work properly.
• Look for rips and stains on the interior panel of the door and scrapes on the bottom edges.
  

Windows

• See if there are any hairline cracks or tiny holes in the glass.
• Make sure that they move up and down smoothly and if they fit snugly when fully rolled up or down.
  

Tailpipe

• Check if the tailpipe is damaged from poor reversing.
• Examine the rear bumper for excessive soot from the exhaust. If the tailpipe has black gummy soot, this may indicate that the engine has worn rings or bad valves, which could mean expensive repairs.
  

Tires and Shock Absorbers

• Check the tires (don’t forget the spare) if they are unevenly worn as this may indicate either bad alignment or worse – damaged suspension.
• Put your full weight on a corner of the car and release – if the car keeps rocking up and down, be wary about the condition of the shock absorbers.
  

Interiors

• Check if the steering wheel points straight when the wheels are aligned ahead.
• Check the upholstery for cigarette burns, rips, stains or scuffs. Low mileage readings but worn out driver’s seat and brake and accelerator pedals could mean that the odometer has been tampered.
• Musty smell, dirt under the mat, moisture inside the trunk and watermarks on the interior panels of doors are likely indicators of flood damage.
  

Lights and Mechanical Devices

• Make sure the lights, air conditioner, heater, windshield wipers, radio and other accessories work properly.

Already sounds like too much work? This doesn’t include checking out the engine and gauging the vehicle’s driving performance yet. That’s a long topic that needs to be addressed in a separate article. Nevertheless, what we’ve discussed could help you unmask any hastily dressed up lemon to reveal its true colors, so to speak.

If you want convenience, buy from a reputable dealer who sells the vehicle “as is.” The dealer does the checking for you, documents all the dents, scratches and damages worth noting and includes the information in the vehicle description. Then all you need to do is negotiate the price.
