"Ordered a remanufactured engine for a 2018 Ford F-150. The quote came in 20 minutes, price was the best I found anywhere, and the engine arrived in 3 days. Perfect condition. Been running great for 6 months now."

"My mechanic told me I needed a new transmission and quoted me $4,000. Found Used Parts HQ online, got a quote for a quality used transmission at half the price. Saved me over $2,000!"
