You guys rock! You picked up the car from our home, took care of biz, texted me a pic of an update. I called and told me that the running light actual holder/bracket burnt out. All in all, still $100 to repair about and you guys dropped it back in the afternoon. Super nice, super convenient with all that's going on with quarantine. I left a positive review on Yelp and posted on Nextdoor that you guys are open. You should maybe let me people know your max radius for pick up/drop off - not sure if it is noted anywhere, luckily I'm just down the street. Thank you! -Jeff

Very professional service with a smile from Susan at the front desk. Great timely service !! Highly recommended.

Kevin Browning and his team at G & M Auto have been great caretakers of my cars for years. They have provided courteous and comprehensive service, as well as good proactive advice that has helped me to make educated decisions about the necessary repairs and costs involved. They really do own up to their motto "Get it Fixed Right!" and have been very diligent in their problem solving, making sure that everything that was a concern to me had been resolved to my satisfaction. I continue to be very satisfied!

Fantastic service and really great prices. When there was a discrepancy between the numbers that were shared with me initially, they honored the cheaper price and were extremely helpful walking me through the repairs.

BRILLIANT SERVICE! WE LOVE YOU SAM! Monica and Patrick! Monica Reed

I got my latest set of new (Michelin Defender) tires today along with alignment on my 2013 Prius. The car noise levels, steering, and ride are much improved. I can't say enough about the personal attention, excellent values and great service at Grand Prix. I highly recommend Grand Prix Tire for your automotive needs. Grand Prix is an honest and competent place of business. Jon D E. Monterey Park, CA 2013 Toyota Prius

Great for getting a Mercedes Service A.

Great Price, Quick, and Honest place. My 200 Ford Explorer has passed with no BS for the past 8 years.

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!!!!!!!

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
