These guys were so amazing! I severely needed an oil change and they got me in right away. They were efficient, kind, and didn’t try to push sales, which I really appreciate. My rating for them is 5/5, for sure!

AG picked up and delivered my girlfriends car once they changed the oil. They were right on time to pick the car up, they even cover the seat and wear gloves while in your car. I was surprised how much they did during an oil change. During the oil change they even informed me about a light that was burnt out and didn't even try to upsell me on it like other shops do. I will bring or have my cars picked up and brought to this shop from now on. It was such a easy process!

I took my 2008 Chevy Duramax into AG Automotive when it was having some hard start and engine misfire issues. Turns out I needed new glow plugs and also had some bad wiring issues. AG took care of my truck quickly and even ended up saving me some money off the original estimate. AG stayed in constant communication with me while my truck was there and took care of it quickly and professionally. AG had been recommended to me based on their Diesel expertise and they lived up to their billing. The cost and professionalism were just an added bonus. Highly recommend these guys for Diesel repair and now that I know they also do gas vehicles, I'll be bringing in my girlfriend's Jetta from now on. Thanks AG!

I've been using AG Diesel since 2012 (4+ years) and they really do superior quality work. From general maintenance, to great advice, and even half an engine rebuild due to a bad head gasket, the parts they choose and the work they do is top notch.
