Car part distribution businesses source, store and supply components and related products for cars and other light vehicles. They typically serve garages, vehicle repairers, motor factors, retailers and, in some cases, members of the public. Stock may include original-equipment and aftermarket replacement parts, such as filters, brake components, batteries, exhaust parts, suspension items, engine components, lighting, oils and other consumables. Distributors use vehicle details, registration numbers or part references to help identify compatible products and may supply technical information, fitting guidance or product catalogues. Orders are fulfilled from warehouses or trade counters, with delivery arranged for workshops and other customers. Some distributors specialise in particular makes, systems or product types, while others carry a broad range of components.
