What Drivers are Saying

Jack Turner

Get mechanics here! They do things the way they used to be done. Very reasonable prices. They quickly and reasonably corrected a problem caused by another local shop.....Well be back for my routine services.

Macy Muzljakovich

I loved my experience at Honest 1 Auto Care Castle Hills! I went in for an oil change and the team took great care of my car. 10/10 service!

Darlene Starr

I've been taking my vehicle to Honest-1 Auto Care for many years and have always received good advise and fair pricing. They always help to put discounts in place when they can. Also very pleasant and kind!

Jennifer Duchscherer

Honest-1 lives up to its name. They have always provided great service, honest information with no hard sell on unnecessary repairs. I trust them and bring all our vehicles there. Very easy to work with and helpful with all issues even if they cannot repair them. You can trust Honest-1!

Had my wheel hub assembly replaced today - best price in town. Sean was very straight forward about pricing, and got me in the next day for repair. Would definitely recommend.

Scott Weeklund

Unfortunately my truck failed me and needed some major timing system work that cost me. But these guys were fast, informative and very good. Steve, thanks. Sorry if I acted like a d&@k. 100k and this. Love the 3.5 ecoboost. Until now.

Kelly Robinson

The people were friendly, appropriately fast, and efficient. Nikita was especially helpful and addressed all of my concerns. They even fixed my friend's tire without an appointment! Highly recommend for quality service.

Bryanna Beal

I am so impressed with my service at this location. Big ups to Brad and the whole team for helping me take care of my car. I will definitely be coming back if I need their assistance. Good communication, reasonable, clean, customer service from the whole team and very informative when it came to my car and what was needed. Thank you!

Rick Klettke

I had an extremely bad experience with Landmark Ford (where I purchased my F150 when new) service and brought my F150 to Honest-1. For the past 2 years they have been honest as the name indicates which is really important to me. They have done major and minor repairs to my truck and always been forthcoming, timely, friendly and informative. I encourage anyone in need to patronize their service centers.
