Extremely satisfied with their service. Eric was absolutely amazing to work with. Fast, clean work and very competitive pricing. They beat every other quote I got for a mobile battery replacement by a meaningful margin. Thank you to the whole team and especially to Eric.

Erick was a great mechanic, very professional, knowledgeable, and communicative. He worked on my BMW 5 Series, which had a coolant leak, and did a great job.

I am absolutely 100% satisfied with the service I received from Eric! He was transparent, honest, professional, and his customer service was truly on point. I’m currently looking for a new vehicle, and Eric performed a diagnostic inspection on a vehicle I was considering purchasing. Unfortunately, after the inspection, I decided not to move forward with the purchase—but I’m still looking! I will definitely be contacting Eric again to inspect my next vehicle before I make a purchase. I highly recommend his services and wouldn’t hesitate to use him again. Thank you, Eric! You rock! 🙌🏽👏🏽

Erick is the absolute best. He's incredibly honest and upfront about any issues, and clearly only wants what's best for your car without pushing any unnecessary problems to get money out of you like many mechanics tend to do. Don't think twice, and go to Erick!
