Where to sell a used engine varies depending on the type of engine being sold. Generally, automobile engines can be sold to auto salvage businesses and websites, such as AAMidwest.com. Engines sold to salvage businesses are typically sold for parts, or exported whole if the engine is in good condition.
Complete engines can be sold on auction websites, such as eBay.com. EBay allows users to sell new or used engines and parts. Commercial and industrial-grade engines can be sold to construction and power equipment companies, such as Quinn Company. These are typically large engines used for power equipment that must comply with state laws.
