Comprehensive Guide to Auto Parts & Dealerships

Understanding Auto Parts and Dealer Networks

The automotive parts sector ranks as the second-largest segment in the global vehicle industry. It encompasses manufacturing, distribution, remanufacturing, retailing, and aftermarket services for auto parts, including installation, chemicals, and accessories. Auto and truck parts may be produced by original equipment manufacturers (OEMs) or third-party suppliers.

The aftermarket automotive segment offers two main categories: replacement parts and accessories. OEMs typically replace worn or damaged parts, while accessories enhance safety, comfort, or aesthetics. Leading dealerships such as Autozone, Napa, Rick’s Auto, SAP USA, and others are prominent nationwide.

Manufacturers produce a wide variety of auto parts, often providing DIY options for car owners with technical skills. This approach allows drivers to perform repairs themselves, saving costs. The automotive aftermarket industry is valued around $320 billion, employing approximately 4.2 million people across manufacturing, retail, and service sectors. Since 2015, demand for auto parts and accessories has continued to grow.

Customization remains popular among consumers. However, availability of specific accessories depends on dealer inventory and procurement channels, including international sources. Dealerships often act as intermediaries, negotiating deals and sourcing parts from global suppliers. Some top dealers can leverage regional market advantages for better service and pricing. Online platforms like eBay and Amazon have further expanded access to auto parts, offering convenience with home delivery options, boosting industry growth since 2014.
