You can get car body parts from several primary sources: dealerships, auto parts stores, online retailers, salvage yards, and specialty manufacturers. The best choice depends on your budget, whether you need a new or used part, your vehicle's make and model, and how quickly you need it. For common repairs, large chain stores or online marketplaces often offer the best balance of availability and price. For older, rare, or specific-model cars, salvage yards or specialty outlets become more necessary.
Dealerships offer Original Equipment Manufacturer (OEM) parts, meaning they are made by the same company that supplied the car when it was new. The main advantage is a guaranteed perfect fit and finish, but they are typically the most expensive option. This is often the best route for newer cars under warranty or when matching paint exactly is critical.
Major Auto Parts Chains like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts stock a wide range of common aftermarket body parts (like mirrors, headlights, and bumpers) for popular models. They offer a good mix of convenience and affordability, with many stores providing same-day pickup.
Online Retailers are a massive resource. Websites like RockAuto, CarParts.com, and even Amazon offer extensive catalogs. The key advantage is price comparison, but shipping costs and wait times are factors. Always double-check part numbers and compatibility before ordering online.
Salvage Yards (also known as junkyards or pick-and-pull lots) are the go-to for affordable used parts. You can find OEM parts for a fraction of the dealer cost. The downside is the part's condition is "as-is," and finding the exact color and undamaged part for your specific car can be time-consuming. Services like Car-Part.com aggregate inventories from thousands of yards across the country.
| Source Type | Typical Cost | Part Condition | Fitment Guarantee | Best For |
|---|---|---|---|---|
| Dealership (OEM) | Highest | New | Excellent | New cars, warranty work, perfect paint match |
| Online Retailer | Low to Medium | New (Aftermarket) | Good (check compatibility) | Budget-conscious shoppers, DIY repairs |
| Auto Parts Store | Medium | New (Aftermarket) | Good | Immediate need, common parts |
| Salvage Yard | Lowest | Used | Variable (as-is) | Older cars, budget repairs, discontinued parts |
| Specialty Manufacturer | Varies | New (High-quality) | Excellent | Performance upgrades, restoration projects |

Start by checking rockauto.com. Their catalog is huge and prices are usually the lowest online. I just type in my car's info, find the diagram for the body section I need, and order the part. It shows me multiple brands at different price points. The shipping can add up, but even with that, it's saved me a ton of money over the years compared to walking into a local store. For something I need today, I'll hit up an AutoZone or O'Reilly's.

My first stop is always a salvage yard, especially for my older truck. New parts from the dealer are crazy expensive, if you can even find them. I use a website that searches all the local yards. You call them up, give them your car's VIN, and they'll tell you if they have a matching fender or door in the right color. It's not brand new, but it's the original factory part for sometimes a tenth of the price. You just have to be okay with a little wrenching to pull it off the donor car yourself.

For a perfect repair, especially on a newer vehicle, I insist on OEM parts from the dealership. Aftermarket parts from chain stores can have slight fitment issues that a professional eye will notice. The bumper might not line up perfectly, or the paint might not adhere the same way. That difference matters when you're trying to maintain the car's value. For a daily driver, a quality aftermarket part might be fine, but for anything I care about, it's worth the extra cost to get the real thing from the dealer.

Don't forget about eBay Motors. It's a wildcard, but you can find everything from individual sellers parting out cars to small businesses selling new aftermarket pieces. I found a brand new, still-in-the-box factory headlight assembly for my son's car there for half what the dealer wanted. The key is to be super careful—check the seller's rating, scrutinize the photos, and confirm the part number matches your vehicle's manual. It requires a bit more diligence, but the deals can be unbelievable.
