Yes, you can absolutely sell car parts, and it can be a profitable venture if you understand the different avenues available. The core of this business lies in identifying the right platform for your specific parts, whether they are brand new, used but functional (often called "used OEM"), or even for salvage. The process varies significantly based on the part's condition and your target customer.
For common wear-and-tear items like brake pads, air filters, or spark plugs, online marketplaces are your best bet. Platforms like eBay Motors, Amazon, and specialized sites like CarParts.com cater to DIY enthusiasts looking for affordability and convenience. Success here hinges on clear photos, accurate descriptions including the vehicle's make, model, year, and engine size (often referred to as fitment data), and competitive pricing. Researching sold listings for similar parts can give you a realistic price point.
If you're dealing with more valuable, rare, or performance-oriented components—such as a turbocharger, a limited-slip differential, or factory alloy wheels—niche forums and Facebook Groups dedicated to specific car models (e.g., Civic enthusiasts, Jeep Wrangler owners) can yield better returns. Buyers in these communities are often knowledgeable and seeking specific parts, willing to pay a premium for hard-to-find items.
For non-functioning parts from a damaged vehicle, you can sell them as cores. Many auto parts stores and rebuilders offer a "core charge," which is a refund you get for returning an old part. They remanufacture these cores for resale. Alternatively, listing the entire car as a parts car on Craigslist or Facebook Marketplace can attract hobbyists or small garages looking for a cheap source of components.
| Platform | Best For | Key Consideration | Potential Profit Margin |
|---|---|---|---|
| eBay Motors | Rare, Used OEM, Performance Parts | Shipping costs and complex fitment data | High for rare items |
| Amazon | New, High-Demand Consumables | Fulfillment by Amazon (FBA) fees | Low to Moderate |
| Car-Specific Forums | Enthusiast-Focused Parts | Building a reputation within the community | High (knowledgeable buyers) |
| Facebook Marketplace/Craigslist | Large, Heavy, or Local Pickup Items | Safety and haggling with local buyers | Varies widely |
| Auto Parts Store (Core Return) | Non-Functional Cores (e.g., alternators) | Instant, guaranteed small return | Very Low (refund only) |
Ultimately, your success depends on honest condition reporting, understanding shipping logistics for heavy items, and knowing your part's true market value.

Oh, for sure. I've cleaned out my garage a few times by selling old parts online. The key is to be honest. Take really good pictures from every angle, especially of any scratches or wear. Just list exactly what it came off of—year, model, engine size. People get really specific. I stick to Facebook Marketplace for big, heavy stuff to avoid shipping, and use eBay for smaller, weirder parts that someone across the country might be hunting for. It’s easy cash for stuff just sitting around.

From a business standpoint, it's a viable model but requires strategy. The primary challenge is managing inventory and fitment data accurately. You must invest in a system that tracks which parts fit which vehicles to avoid returns. Focus on a niche, like classic Mustang parts or import performance components, to build a reputation. Leverage Amazon and eBay for volume but consider a dedicated e-commerce site for brand building and higher-margin . Customer service is critical; positive reviews drive repeat business in this competitive space.

As a mechanic, I see both sides. People are always looking to save money on parts. If you have a good, used original equipment manufacturer (OEM) part from a car you're scrapping, someone will buy it. It's better than a cheap aftermarket part. But you have to test it first. Don't sell a window motor that doesn't work. Be prepared to answer technical questions. I often tell my customers to check forums for used parts because the sellers there usually know what they're talking about.

Absolutely. I started by selling the factory wheels and tires from my new truck—they were just taking up space. I was surprised how quickly they sold. The market is huge for take-off parts, items people remove from a brand-new vehicle to customize it. Think wheels, suspension kits, even spoilers. The condition is usually like-new, and there's high demand. Just be patient. Price it fairly based on what others are asking, and be clear about pickup or shipping. It’s a great way to fund your own car projects.
