General Parts Group is a wholesale distributor that sells automotive parts to repair shops, not directly to consumers
General Parts Group (GPG) is one of the largest automotive parts distributors in North America. It operates through several brand names you may have heard of: NAPA Auto Parts, Carquest, and Autopart International. These are the storefronts and warehouses that mechanics, body shops, and fleet operators buy from — not the places where individual car owners typically shop for parts.
If you take your car to a repair shop and they order a part, there is a good chance it comes from one of GPG's distribution centers. The company sits between manufacturers (who make parts) and the shops that install them. Understanding how GPG works helps explain why your mechanic may quote you a certain price, how long a part might take to arrive, and what options exist if you need something urgently.
Key Takeaways
- General Parts Group operates NAPA, Carquest, and Autopart International — three separate retail and wholesale brands that serve repair shops and mechanics.
- GPG sells primarily to businesses (shops, fleets, dealers) rather than to individual car owners, though some NAPA locations do sell retail.
- When your mechanic orders a part, they often source it through one of GPG's distribution centers, which affects price and delivery time.
- GPG's network includes thousands of locations across North America, so parts availability and shipping speed depend on which warehouse serves your area.
The three main brands under General Parts Group
NAPA Auto Parts is the largest and most recognizable brand. NAPA operates both retail stores (where consumers can walk in) and wholesale operations that serve shops. Not every NAPA location is the same — some are primarily retail, others primarily wholesale, and many do both. A NAPA store in a small town may look like a traditional parts counter, while a NAPA warehouse in an industrial area serves dozens of shops daily.
Carquest operates similarly but has a different geographic footprint and customer base. Carquest locations tend to be concentrated in certain regions and often serve independent repair shops more than large chains. Like NAPA, Carquest has both retail and wholesale operations, though the balance varies by location.
Autopart International (API) is the third major brand and operates primarily in the Northeast and Mid-Atlantic. API serves a similar wholesale and retail mix but has a smaller overall footprint than NAPA or Carquest. All three brands are owned by General Parts Group but operate as separate companies with their own inventory systems, pricing, and customer relationships.
How parts flow from GPG to your mechanic's shop
When you bring your car to a repair shop, the mechanic diagnoses the problem and determines what parts are needed. If the shop does not have the part in stock, they contact a supplier — often a NAPA, Carquest, or API location. The shop has an account with that supplier and can order parts on credit, usually with payment due within 30 days.
The supplier checks their local warehouse inventory. If the part is in stock, it can be ready for pickup or delivery the same day or next morning. If not, the supplier checks GPG's larger regional distribution centers. Parts move through this network based on demand, so common items stock locally while specialized parts may come from farther away. This is why your mechanic might say "I can get that part today" or "that will take three days."
Pricing works through a tiered system. Shops that order frequently or in large volume get better prices than shops that order occasionally. GPG sets wholesale prices, and individual shops negotiate their own discounts based on volume and loyalty. This is why two shops in the same town might pay different amounts for the same part — and why the price your mechanic quotes you includes their markup on top of what they paid GPG.
Why GPG's size matters to you as a car owner
General Parts Group's dominance in the wholesale market means that most independent repair shops have limited alternatives. A shop owner typically has accounts with one or two major distributors because maintaining multiple accounts is costly and complicated. If GPG raises prices or has supply problems, shops feel the impact directly, and that cost often gets passed to customers.
The size also affects parts availability. GPG's network is large enough that common parts move quickly, but specialized or rare parts may take longer because they stock less frequently. A shop in a rural area may have slower access to parts than a shop in a city, straightforward because the nearest GPG warehouse is farther away or serves fewer shops.
GPG's ownership of multiple brands can also create confusion. A shop may have accounts with both NAPA and Carquest, but the two systems do not share inventory in real time. A part that is out of stock at one location might be available at the other, but the shop has to check both systems separately. This fragmentation, while it exists for business reasons, can slow down the parts-ordering process.
What happens when GPG experiences supply disruptions
Like all distributors, General Parts Group depends on manufacturers to supply parts and on logistics networks to move them. During periods of high demand (like after major weather events) or supply chain disruptions, GPG's warehouses can run low on stock. When that happens, repair shops face longer wait times, and customers end up waiting longer for their cars to be fixed.
GPG has invested in technology to manage inventory across its network, but the system is not perfect. Parts can be stuck in transit, manufacturers can delay shipments, and demand can spike unpredictably. Shops sometimes deal with this by ordering from multiple suppliers or by suggesting alternative parts to customers. Understanding that your mechanic's timeline depends partly on GPG's supply chain can help you understand why repairs sometimes take longer than expected.
How to find a GPG location near you
If you want to find a NAPA, Carquest, or API location, each brand has its own store locator on their website. NAPA's locator is at napaonline.com, Carquest's is at carquest.com, and API's is at autopartsinternational.com. These tools let you search by zip code and show you which locations are nearby, their hours, and sometimes their phone numbers.
Keep in mind that not all locations sell retail to consumers. Some are warehouse-only operations that serve shops exclusively. If you call ahead and ask whether they sell to the public, they can tell you whether you can walk in and buy a part or whether you need to go through a shop. Many NAPA locations do sell retail, but policies vary by franchise owner.
If you are looking for a specific part and want to check availability before driving somewhere, calling ahead is your best option. Locations can check their inventory and tell you whether they have it in stock or how long it would take to get it.
Frequently Asked Questions
Can I buy parts directly from General Parts Group as a consumer?
Some NAPA locations sell retail to consumers, but Carquest and API locations are primarily wholesale. Your best option is to call a nearby NAPA store and ask whether they sell to the public. If they do not, you can buy from a retail parts chain like AutoZone or O'Reilly, or you can ask your mechanic to order the part for you.
Why is the price my mechanic quoted me higher than what I see online?
Your mechanic's price includes their labor markup on top of what they paid GPG for the part. They also factor in their overhead, warranty, and the convenience of having the part ready when you need it. Online retailers often have lower prices because they operate differently and do not provide installation or support.
What if my mechanic says a part is on backorder?
A backorder means GPG does not have it in stock and is waiting for the manufacturer to send more. This can take days or weeks depending on the part and the manufacturer. Your mechanic can sometimes suggest an alternative part or check with other suppliers, but backorders are common during supply disruptions.
Do NAPA, Carquest, and Autopart International have the same inventory?
No. Each brand has its own inventory system and warehouse network. A part available at NAPA may not be available at Carquest, or it may be in a different location. This is why shops sometimes have accounts with multiple suppliers — to increase their chances of finding parts quickly.
How long does it usually take to get a part from GPG?
If the part is in stock at a local warehouse, it can be ready same-day or next morning. If it has to come from a regional distribution center, it typically takes two to five business days. Delivery time depends on distance, the part's popularity, and current demand on the supply chain.
