Planning to buy a used car? Here are five things you should check to get your money’s worth:

 

Mileage

One of the first things you should check is the car’s mileage. It tells you how much the car has driven. More miles indicate more stress on the car and low mileage means less wear and tear on essential components. 

The average person drives 13,476 miles each year, and 13,000 to 15,000 miles is a good benchmark. Make sure there is no odometer tamper by comparing current and past odometer readings. 

Keep in mind that buying a car with extremely low mileage isn’t always a good idea as it is a sign of long periods of inactivity which might lead to battery. Buying a high mileage isn’t a bad idea as long as it has a regular maintenance and service history. 

 

Availability of Spare Parts

One of the most overlooked considerations when buying a used car is the availability of spare parts. Some car models may have limited parts, which can make repairs expensive and time-consuming. 

Once you’ve narrowed down the car models you’re interested in, search online marketplaces and auto parts stores to see if the essential components are available. Many reliable auto parts stores, such as Ovoko, have millions of OEM parts, saving you time and money. You can check the website to find the best quality spare parts for your soon-to-be car. 

 

Car’s Exterior Condition

Next, inspect the car’s exterior. Take a thorough look at the car’s body to identify signs of past accidents, rust, or hidden damage. Paint inconsistencies, such as mismatched paint color and uneven texture, are clear signs of previous damage. Look for dents, cracks, and scratches, especially on the bumper and doors.

You should also inspect the windshields, side windows, and rear windows for chips and pocked areas. Lastly, make sure the headlights and taillights are working properly. 

Remember that minor damages to the exterior of the car aren’t usually a deal breaker but they can help you get a lower price. 

 

Car’s Interior Condition 

Next, inspect the interior of the car. Start with the seats – check for any tears, cracks, and stains. Make sure the adjustment features of the seat, including recline and lumbar support, are working properly. You should check the car’s:

  • Ignition
  • Dashboard lights
  • Warning lights
  • Bluetooth
  • Radio
  • Heating and cooling system
  • Airbags 

Lastly, inspect the overall cleanliness inside the car. A must odor is quite common and is a sign of water damage inside the car. Check under the floor mats for dampness caused by leaks. 

 

Car’s Mechanical System

Inspecting the mechanical system of a car can give you an insight into its performance. Here’s what you need to check:

Engine Condition 

Pop the hood and inspect the engine for corrosion, leaks, and worn-out parts. Check the engine oil and coolant levels. Leave the engine on for a couple of minutes and listen for rough noises and excessive vibration. 

Braking System

Brakes are one of the most important safety features in a car. Make sure the car is stopping smoothly without any grinding, squeaking, and vibrations. Check the brake fluid level and inspect for leaks. 

Suspension and Steering

If the car bounces too much over bumps or shifts to one side, there might be an issue with its suspension system. Check the condition of the steering wheel as well to see if it’s too loose or stiff. 

Unless you’re a serious car nerd, it is best to get the car inspected by a mechanic. They will find underlying issues and red flags that you might miss on your own.
