Loved working with the guys at this shop. They were honest with the repairs I needed and didn’t need at the time.

I had a great experience with the gentlemen that work at RX Automotive. They are honest and trustworthy. They went the extra mile and tighten some bolts that I didn't do myself, on a part of the car that I didn't even bring it in for. Had they not done this, it could have been a real bad situation for my family and I. I will be taking both my cars here in the future.

My sister has been coming there for maybe five years with her jeep and I needed my axle boots replaced, they were leaking so I went there. They showed me pictures of everything they done what they found what needs to be addressed now what needs to be addressed later , the price was fair and I talked to the mechanic. The top half of my engine, the gasket was leaking they replaced that that was a fair price. Overall, I gave them a five star rating, very professional, very polite and I would recommend them and like I said I will be back. He said my car is in great shape. Just their honesty goes a lot with me and goes very far down the road. A mechanic is my best friend and I appreciate them taking care of my car. My sister’s car will I be back absolutely I have some things that they addressed and he goes. We’ll address them as needed so when I go there next month, I’m gonna say what needs to be addressed now and we’re gonna take care of that and anything that needs to be addressed later, we’ll deal with

They are professional in how they inspect your vehicle, how they present the issues and how they treat you as a customer. They don't treat you just as a customer but as that good neighbor who is always willing to help anyone. RX continue too do it how your doing it, Great!

This was my first time at this shop and I was very impressed with their service. They honored my after market warranty and was able to get them to cover the repairs better than I thought they would. This saved me more than half of the repair bill. I will be using them again for my next service.

Response from the ownerAwesome, Mark! I'm so glad the guys were able to take care you! We look forward to seeing you again. Take care.

Diego was very courteous , explained well what was needed to be repaired and the estimated cost. . They were conscientious about making the necessary repairs and keeping the cost down to what was necessary. They also inspected the entire car and suggested some future repairs, so I’m aware of potential future problems. My family and I will definitely come back . I highly recommend this business.

Response from the ownerThanks for the review, Elio! We look forward to seeing you again.
