We took our vehicle, a ford diesel, to Justin on several occasions. One of the first visits was for a bad pinion bearing in the rear end. While inside doing the repair, Justin found other issues, which he seemed to support with facts, and would cost more money to repair. We agreed, but when we got the truck back, it had a bad vibration that wouldn’t go away. 2 more visits, but Justin was unable to find the root cause of the problem, and assured us it wasn’t his fault. Fast forward to now, and the rear has come apart. Now at a different reputable repair shop, the truth comes out. It wasn’t

Justin was recommended by several friends who have used his services for years. I'm glad they did, since I have been going to his shop for all of my work, and I have been completely satisfied every time. He is very professional; he always lets me know if any additional work is required, and his prices are fair. I gave him five stars!

Justin has worked on our vehicles and has always done a great job! It's hard to find a good vehicle repair shop that you can trust and Antietam Automotive has always treated me well. Justin always contacts me first with a price to fix the vehicle and he is very fast with all of the repairs that needed to be done. I couldn't ask for any better. Thanks Justin!

My husband and I are new to the area and we were looking for a new mechanic. Unfortunately, we needed to find one sooner rather than later when my car wouldn't start one morning. My husband called Antietam Auto because its .6 miles from our house. They gave us the number to a great tow company that they usually work with and I had my car towed there within the next day. By the end of the day, Justin had diagnosed that I needed a new starter and had ordered it right away. He had my car fixed and ready to go by 10am the next day! I was blown away by how fast he fixed my car and by the low price he

Great customer service! I am across country from Justin over in Oregon, i have done countless deals with him, ordered tens of thousands in parts and customer service has been amazing, when i call for questions he is there for me even when he is not making anything, which is probably 2 times a week for the last 2 years. I recommend them to anyone and everyone, thanks for the continued support Justin.

Greatest experience ever dealing with a mechanic. The guys here are honest and outstanding in their work. I would recommend this place to anyone, i am a veteran and it makes me feel proud that i fought for these guys freedom's, without them they may have never opened their shop. I was treated so well by Justin he kept me informed and worked with my budget to get me on the road again, many thanks to justin and his team i really couldnt be any happier i am a customer for life. My truck runs better then the day i bought it. I owe these guys more then they charged me, you cant put a price on piece

Have been taking my f250 to Justin for about 3 years and haven't had a bad experience yet. He's done a transmission, and engine build/tune for me and they are working flawless after 30k miles. Justin answers questions quickly and goes out of his way for his customers. Couldn't be much happier and wouldn't recommend anyone else for your diesel needs.

I have been a consistent customer for nearly 10 years simply for my satisfaction on completion. Justin and his employees have been nothing but like family and more than willing to go above and beyond Anything I requested of them. I've brought all of my vehicles to Antietam and each time same result, never a disappointment and always provided with professional craftsmanship and execution in a timely manner. I've even brought my high performance diesel pickup to them for custom suspension, drivetrain, motor, and full on transmission work all for the best prices around. Thank you Justin and Antietam
