Great group here!

The sales crew are really receptive and extremely knowledgeable. The whole process went smoothly and my engine showed up exactly as described. Highly recommend these guys.

Finding a reliable used engine supplier...

Finding a reliable used engine supplier is never easy, but Auto Power Source completely changed my perception. From the start, their team was responsive and patient, answering every question before I placed the order. The engine I received was exactly as promised — clean, complete with all accessories, and ready for installation. My mechanic even pointed out how carefully it had been dismantled and shipped compared to others he has seen. What impressed me most was the follow-up — they didn't just deliver and disappear. They checked in to make sure the engine arrived on time, fit properly, and that I was 100% satisfied. It's rare to find this level of accountability and customer care in the auto parts industry. If you're considering an engine or transmission replacement, I highly recommend Auto Power Source. They've earned my trust and will be my go-to for any future needs.

Smooth transaction

After searching for a ford f150 motor, Auto Power Source showed up online and appeared to have the one I needed, with relatively low miles. After making contact, Alan responded and from there the purchase was seamless. He made sure the engine was correct through VIN number, communication was excellent all the way through to delivery. Alan sent pictures of the vehicle the engine was coming out of, as well as the engine right before it was shipped. I chose to purchase from Auto Power Source because they are somewhat local to me, they had a great price, excellent communication, & quick shipping! I will recommend this company, and I will also buy from Auto Power Source again!! Great job Alan!
