This is one place on where I will be a FOREVER Customer and Loyal at that. Today I had the wrose most horrible day dealing with a set of bad companies that deal with tires. I was out and about for almost 8 hours trying to get my tires replaced due to one of them having a Bad Factory tear on the inside of the tire. I got here at 6:45pm, right before they closed and this AMAZING WONDERFUL Gentleman asked me how I was doing and was super sweet to hear what happened. He said he was sorry for what happened and that he would be happy to help. Within minutes of getting there, the guys out in the garage did the alignment, changed out all 4 tires and also told me that I had 2 other problems with the Tire area and helped me in every way to get my car back on the road safe for me to drive. It took these gentlemen 40 min.s to get it all done right. They helped me with everything, got me a warranty on the tires and more. I couldn't have been anymore happier, they made my day better. Thank you guys for the help and can't wait to come back to get more service done on my car. Krystel Carrilo

First and foremost Sean is really good at fixing cars!! He knows his stuff. His way of explaining the mechanics makes me feel at ease because I can actually follow. Though his auto mechanical IQ is as strong as anybody else's, it's Sean's integrity and laid-back professionalism that sets him apart in his industry. Sean will NEVER make you feel like your being taken advantage of and He will always tell you the truth...always. Also, his prices are extremely reasonable. I have been using Sean for several years and will continue to do so. I recommend him to anyone.

Freddie was a great help and very respectful. I had a flat and it was closing time and he got my tire fixed right in time super fast so I can get back on the road. A plus service. Richard Ryan

This place was busy right away this morning when I arrived. Still they were able to squeeze me in. I thought I need a tire patched as it was flat. Ends up it was only a bad valve stem. They switched it out in no time and didn't t even charge. I was pretty surprised and quite speechless. Thanks a lot guys. By much appreciate and you'll be seeing me again when it's time for new tires. John Sheridan

Please remove this place from any shop in LA horrible niggle be stealing everyones cars lol !!!! CROOK ALERT

Great service! I was given a detailed understanding of the issue my vehicle was experiencing. With my small budget incapable of undergoing all needed repairs, they made it work. Even better - under what I could spend :) This is a quick, clean, professional, and understanding location of which I highly recommend. Chris Curtis

My charger rides so good after the tune-up they gave me, I had a very long drive so I decided to get a tune-up first, so glad I did! They do amazing work!

These guys got me a good price on a pair of new tires. Install on what looked like it turned into a busy Friday afternoon took about an hour. Rachel Ann Pierce

The service here is amazing. I went to go get my tire patched and they were pretty quick. I didn't have to pay anything I just tipped the man who put my wheel back in. I would definitely come back. Mauricio is very helpful. Edwin Aguilar

Great staff. Great attitude. Great work. Extremely competitive pricing. Wont take my cars to anyone else if I can avoid it. -Sam Rhodes

My first visit for maintenance after my Mercedes warranty expired. The experience was overwhelmingly positive. Herbert has a professional calmness that exudes knowledge and confidence. You are immediately aware that you and your car are in good hands. Herbert's fees are fair and he will tell you exactly what your car needs- and perhaps more importantly, what your vehicle does not need. I am very pleased that I trusted Herbert with my C300 sport package AMG, and expect to return for any and all future service needs. sincerely, Stan Kelley

The staff was friendly and performed the alignment check quickly. I was concerned about possible frame damage on a used car that I was considering purchasing and they directly addressed my concern about that issue instead of simply telling me the car was aligned well. While waiting outside, they got a chair for me to sit in, so that was nice, too. Chris Morris

They have the lowest prices for service and they are very friendly. I've been using them for years and always satisfied. Mark Nelson

Shady shop in Glendale must avoid. I went in for some new tires. They continuously changed the price quote and switched tire brands. They insisted that I need an alignment and new control arm bushings or they won't provide warranty on the new tires. I allowed them to change the bushings and do an alignment and after a couple of days the car drives terribly. It pulls to either right or left side at highway speeds and intermittently there is a wobble on the front right wheel side. I took the car back and after their "mechanic" test drove they tell me I need new brake rotors and need new brake system. This is so bogus because when they worked on my car initially they said everything is fine we checked brakes, etc, etc, etc. My car was driving fine before they worked on my car! I just needed new tires. So now my car has a wobble and alignment is off and they wont fix the work they did. They want to charge me for more things that I don't need instead of replacing the cheap aftermarket bushings they put in. Really sad just avoid this place. Just let them fix your flat tires nothing more. CHECK THEIR BBB! ALL THEIR STORES HAVE 'F' RATING AND THE GLENDALE LOCATION DOES NOT EVEN HAVE BBB! How is this shop still open I have no idea...

We went through 3 different mechanics including the Mercedes Service Department before going to Gold Star. Mike diagnosed the problem with no charge, and his findings were very accurate. We had spend close to $2000 fixing what wasn't even the issue, even Mercedes charging us 280 for diagnosis still couldn't fix the issue. I am so happy and grateful to Mike, he was so generous, professional, experienced, and courteous, we've finally found an honest and extremely experienced mechanic. I will recommend Gold Star to all my friends and family. I rate Gold Star a 10!!!!!!!
