Online used car parts seller

DIY drivers, restorers, independent repair shops and body shops looking for cheaper or hard-to-find parts.

You sell each part for more than you paid plus shipping and fees. Margins are best on in-demand parts for popular models and on parts you can fit-check accurately.

• Basic mechanical knowledge and comfort with tools
• Matching parts to makes, models and years
• Clear photos and honest listings
• Packing and shipping bulky items

• Check whether your state requires a dealer, dismantler or recycler license to buy and sell used parts in volume, and ask your state DMV or licensing board
• Rules on catalytic converters and salvage or title parts are strict in many states, so check what records or restrictions apply before you buy or sell
• Check your marketplace's policies on safety parts such as airbags, which are often restricted
• Register for a seller's permit or sales tax number with your state if required, and check what your marketplaces collect for you
• Store fluids, batteries and heavy parts safely, check local rules on disposal, and check HOA or lease rules and zoning if you store stock at home
• Returns and wrong-fit claims can eat profit, so list part numbers carefully and consider general liability insurance

Startup costs are typically around $1,500 to $7,500, depending on the tools, storage and shipping supplies you need and how much stock you buy at first from salvage yards, auctions or local sellers.

Monthly revenue is typically estimated at around $800 to $4,000, depending on the parts you sell, your prices and how much time you put in. The estimate assumes at least about 10 hours a week. Returns and wrong-fit claims can reduce profit.

Check whether your state requires a dealer, dismantler or recycler license to buy and sell used parts in volume, and what rules apply to catalytic converters and salvage or title parts. Also check marketplace policies on safety parts like airbags, and whether you need a seller's permit.
