Replaced engine in my subaru outback with 220,000 miles. Got a very low-mileage (85,000) and well packed, good engine. Installation process went well. Highly recommnd Car Part Headqurters to you.

My son needed a used transmission for his Acura TL, they are good people, prompt and genuine, and helped over the phone. I got the engine shipped to our shop and it fit in my car and in great shape! My car now runs great, awesome service, will recommend them to anyone in my shoes.

Got a new engine into my Honda Accord it was a complete motor with all except the starter. Car Part HQ did an awesome job. The engine was on time when I needed it. Strong compression and just what they said it would be. Bravo!!! Will certainly do business again if the need arises, highly recommended.

They were super responsive in every aspect of the sale and my transmission arrived in three days, I was blown away. The  transmission was exactly as they said it would be and in great shape, and the price was right in my budget too.

I bought a used transmission for my car. They answered me all the time and toughed me more than I wanted to know. The transmission came and my car is out on the road. Great service and I would recommend them to anyone.

Ryan was most helpful in my regional search for the purchase of a used engine. He has considerable knowledge of the used parts business. I'd definitely buy from him in the future. His website will be bookmarked 1st for my vehicles parts.

Car Part HQ is ABSOLUTELY amazing!! The prices are reasonable and every person I've talked to has been knowledgeable, nice, and eager to help. If I could give them more than the five stars I for sure would. A special THANK YOU to David and the rest of the guys for making the ordering process so easy. Especially for someone like me that does not know much about engines and how they work.

Ryan at Car Parts Headquarters went above and beyond my expectation in helping me track down a frame for my 1968 GTO. He was able to give me a contact number as to where I can get this part. According to my conversations with him this is a very hard part to find. Thanks again Ryan for hour help. They get a 5 star rating from me for his help. Mike Johnson

Tony was very helpful and went the extra mile to assist me and I appreciated that very much.

I'm very glad I found Car Part Headquarters! I had been looking for weeks for a transmission for a mitsu outlander, and even the car repair shops here couldn't find one. Car Part Headquarters found one at a reasonable price, and got it here on time! Great people to work with, and I recommend them! - Jon , Lake Orion Michigan
