TESTIMONIALS

Drove up Sierra ave looking for a mechanic and I found who was more than glad to help me out, he is going to replace my front two lower control arms and axle, his price that he gave me after deducting a couple hours of labor was more than reasonable, a little more work than we thought so the car has to stay over night, roger offered me a ride home so I wouldn’t have to take an Uber I thought that cool of him so we’ll see you tomorrow..

I don't normally leave reviews but felt I got Great service at GSS Auto Repair. He found the problem with my truck that nobody else could figure out. It turns out I needed a steering box, not only did he fix it, he went over the brakes checked all my fluids and belts to make sure I didn't have any problems down the road. He is now my new mechanic for all my vehicles. You can't go wrong with GSS Auto Repair. Thank You!

I Called GSS Auto Repair And Told Him My 2006 4-Runner Rear Brakes Were Metal To Metal. I Arrived Exactly 48 Minutes After The Call And He Had My Brake Pads And Rotors Ordered Already! He Had Me Done In 36 Minutes While I Waited! He’s Fast Efficient And Good At What He Does! I Really Appreciate That He Is An Honest Christian Too! I Highly Recommend GSS Auto Repair To All Who Reads My Review!
