Top 5 Most In-Demand Used Auto Parts – And Why You Should Buy Them Used

When it comes to car repairs, you don’t always need to buy brand-new parts. In fact, buying used OEM auto parts is a smart, cost-effective solution—especially for components that are frequently replaced or damaged.

At Bigansto in Lithonia, GA, we stock thousands of high-quality used parts and ship them nationwide. Here are the top 5 most in-demand used auto parts—and why buying them used just makes sense.


1. Engines and Transmissions

These are two of the most expensive components to replace, often costing thousands when purchased new. But used engines and transmissions—especially those with low mileage and verified testing—offer huge savings without sacrificing performance.

At Natty Auto Parts, we test all our powertrain components to ensure they’re ready to install and run reliably. We also offer part-matching support, so you don’t risk compatibility issues.


2. Headlights and Taillights

It only takes one minor accident or parking mishap to damage a headlight or taillight. While new lights from the dealership can cost hundreds, used OEM lighting matches your car’s original appearance and wiring—at a fraction of the cost.

Plus, OEM lights ensure consistent brightness, fit, and longevity, unlike many aftermarket options that may not seal properly or wear out quickly.


3. Bumpers and Fenders

Whether you’ve been in a fender bender or need body parts for a restoration, bumpers and fenders are top-selling used items. Why pay for a brand-new body panel when you can get an OEM-fit replacement—often in your exact paint code—for less?

Used body parts save both time and money during repairs and can help maintain your car’s resale value by preserving factory specs.


4. Side Mirrors

Side mirrors are common victims of tight parking spaces, pole scrapes, and careless drivers. New mirror assemblies can be surprisingly pricey—especially for newer models with power controls, heating, and signal lights.

Used OEM mirrors are an easy swap that delivers perfect function and fit. You won’t have to worry about electrical mismatches or incorrect dimensions.


5. Seats and Interior Parts

From seatbelts to dashboards, center consoles to floor mats—interior parts are in high demand for both replacement and customization. If your vehicle’s interior is worn, torn, or stained, used OEM parts offer an affordable way to refresh it.

We carry like-new and gently used interior components for a variety of makes and models. Whether you’re restoring an older car or fixing up a daily driver, we’ve got what you need.
