The test drive is the most important part of the used car buying process, but it isn’t the only thing you need to do when looking at used cars. After the test drive, there are some things you need to do, as well:
With the engine still running, take a look under the hood. Check out the engine. Are there any new leaks that weren’t there before? Are there any odd sounds, or a clattering noise? Are there any unexpected odors, such as the smell of oil or coolant? is the exhaust clear?
Next, check under the car. Look for leaks. Be aware that the air conditioner may leak water, which is normal.
Ask to see the title. Compare the title to the Vehicle Identification Number on the car. (The VIN, which is different for every car on the road, is located either at the front of the dashboard along the windshield on the driver’s side, or on the driver’s doorjamb.)
If possible, call your own mechanic to arrange for an inspection of the vehicle. This will help you to discover any ongoing problems that you otherwise might not have been able to notice, without a mechanic’s expert eye.
