Tony is absolutely amazing. He is honest, trustworthy and I felt comfortable leaving my car with him. Though he didn't fix my problem due to my having a warranty he was happy that my car was getting fixed though not by him. Will def be coming back and referring him to friends and family Cristina R.

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.

Great for getting a Mercedes Service A.

Great work, they charged me hundreds less than the dealership! Nice showroom and friendly guys in the office.

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!!!!!!!

Kevin was very courteous and helpful. Very satisfied so far. Had used Gio in 2015 and was very happy with his work.

I am well pleased with the work performed on my truck! Eddie was real nice and gave me good pricing! Along with my engine rebuild( replaced cracked heads) I received a 2year 24000 mile warranty! I live in San Diego and would refer all my family and friends including you! Happy Motoring! Jack

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!

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

We were referred to Mitch at Schneider's Auto Repair by a family member who has had nothing but good things to say about them. We have taken our cars to Schneider's for the past couple years and have received excellent service from them. The customer service department was extremely courteous to us each and every time. I have referred friends and family to them and will continue to do so!

20+ years I've lived in Los Angeles and have had my Benz worked on far and wide. If I had only known Kevin at MZB West. By referral I have taken several cars to him and my own and have always left feeling satisfied and relieved. Satisfied because the quote is always itemized AND prioritized and relevant. Relieved because his work is thorough, quick, and very reasonable. Fact is the only way you will know this is to go. Thanks for your work Kevin.

Save yourself the time shopping estimates and go here! They are SO nice and do a great job! Even better, after I was struck by another car, they gave me the only sane and fair price out of any of the body shops in silverlake and echo park. Hopefully I don't have to go back, but if anything else happens to my car aram is my go to!!!
