    This is a local business. They have awesome customer service. They were able to do same-day service and they took great care of my vehicle.

    The transmission in my wife's 2009 Cadillac Escalade ESV cratered after 223,000 miles. These guys…read morewere the first and only place I trust for them to work on her transmission. I previously used them in the past for a broken shifter cable. From that inital experience, we could have easily been taken advantage of and been told it was a bad transmission, but their transparency and and honesty is what brought me back. For this transmission rebuild, they called us for every step during the diagnosis, removal, repair, and replacement process. They even requested for me to come to the shop and view the components that went bad. I was not able to make it, so they sent detailed pictures with a phone call afterwards with a detailed explanation of what I was looking at, why it failed, including options for repair. As a "motorhead" myself, everything he described in detail was concise, accurate, and no misleading information was given. My wife and I could not ask for any more. For your transmission needs, please consider this organization to take care of you. Oh, they even washed our vehicle for both repairs and placed several paper mats not to get any grease or grime in the interior of our vehicle (it's the small things that make a difference. That pride for their customers goes a long way! Although we were not expecting to spend this kind of money during the holidays, the experience was positive and we are back on the road with no car note, lol. I'd like to give the service advisor "Tony" for his professionalism and patience, and the owner for approaching me to make sure we have been taken care of. Hands down, best transmission shop in SATX. #Trust #Transparency #CustomerService

    I highly recommend Bert's Gene Brown. I've always been hesitant to let a shop fix my vehicles but I…read moretook a chance and they did not disappoint..I will continue to use them for all future services..

    My daughter is a UTSA student living away from home. She calls me and says her 2018 Hyundai Elantra…read morewon't start but she knows of a mechanic close to her apartment. She has her car towed to Chad Miller Auto Care and calls me to say she needs a new battery and is being quoted $645. I ask her to hand her phone to an employee, and when I asked why this is so expensive the employee raised their voice at me. I asked for a manager and was informed it was Chad himself I was talking to. I would NOT suggest this mechanic. He is unprofessional and perpetuates the negative stereotype of crooked mechanics preying on young women.

    So I read good things about this place. From what I read, they seemed like they knew what they were…read moredoing and maybe they do, but of the two vehicles I took there, both over 10 years old and with a variety of problems, they were able to fix some things,but not all. Mine has an oil leak at least 4 different places haven't been able to figure out. Chad's garage gave me some hope, but they were never able to fix it. I take pretty much all "guarantees" with a grain of salt. "Bring it back"...pffft why would I? You couldn't fix it the First time? More likely, I'll just be dumping more money in sonl you can "half fix it" a 2nd time. One mechanic even told my wife to "hit the dash when her A/C wasn't kicking on...AFTER they fixed it. GTFO... Really!? Cost wasn't exactly on the cheap side...maybe fair, but ONLY if they fix the problem. My impression is they had way more cars than they could handle and were trying to rush them outa there. Fair enough, but I will not be taking either of ours back. Fair warning to those that do.

    10/10 recommend! My family has used them a couple times now. This place could have cost/charged my…read morefamily thousands of dollars and never did. The owner really does pride his business in honesty and integrity! Their customer service was amazing too. My dad got a quote from a different place for $5k for some work the said "needed to be done." He called around for other quotes and ended up at West Ave Auto because over the phone they said they would do the job for HALF the price! When my dad got there it turned out a plug just needed to be removed/drained which was causing the sensor on his truck to act up... Marvin was honest and just charged him the labor fee... Saving him thousands! I had water damage to my car and was scared I was going to pay thousands for repairs on my car too but my dad told me to drop my car off at West Ave Auto. They were honest right away. Didn't try to play off the fact my car could have needed huge repairs. Instead reassured me the damage was minor and they were even able to bend back a part instead of telling me to replace the whole thing. In addition, I knew I needed other work done so gladly gave my business to them. My car was also done the same day! Saving me the hassle of having to worry about paying for a rental and unnecessary stress. On top of it, Marvin remembered my dad, his name and truck. Which is very cool considering how many people I'm sure he probably sees on a day-to-day basis. Honesty and integrity go a long way! This company now has loyal customers and I will be recommending their shop to everyone I know. They also offer military discounts in addition to their affordable prices and great customer experience!

    Called a couple places to get an issue resolved. He was highly attentive and detailed with…read morequestions to what was going on with my car. Had an opening for next day and issue was resolved. I believe this company works with integrity and that is what will keep me coming back. Thank you so much!
