"I have been working with Scott to get a preowned Porsche PPId. I’m from San Francisco area and Scott has gone above and beyond to facilitate the inspection. He’s forthcoming and very communicative. Highly recommend!"

"These guys are great! I brought a car to them 15+ years ago for tuning. Fabryce was friendly and knowledge, and helped me get set up. I come back because I had a good experience."

"One look inside the stable and you know you've come to the right place with your high-end vehicle!! R&D done in house, used in their own cars and then made available to the open market. Excellent customer service and support!"

"I cannot speak highly enough about this shop! I had a shop in Mesa, AZ install new KW coilovers upside down (yes, you read that correctly - see photo), on my BMW. With only a bit of weight in the car, it was topping out badly, and was on the verge of seriously damaging my car. I was in a panic, ...on a tight schedule and Allen at GMG squeezed me in. They repaired my car, installed new tires, set the height properly, and did an alignment. I want to mention, I had probably the cheapest car in their shop (by a factor :), and Allen and the GMG team treated me like I had the most expensive car in their shop. These guys are consummate professionals and I cannot speak highly enough about them! Don't look elsewhere - just go and experience for yourself! Thanks again Allen, and team GMG, you guys are awesome!"

"Not only was I dreaming about buying my first 911 for over 10 years, but that dream included taking my 911 to GMG Racing for some upgrades. Not only did I create a budget for my 911, but for all the modifications that I wanted done. At first I thought about doing the upgrades in stages to test out GMG, but after speaking with Scott Centra I was motivated to do it all at once. His customer service and attention to detail is second to none. Had it non been for him walking me through and coaching me on how to create my dream 911 I would have just had a 911 not my DREAM 911. Hector did amazing work on my car, and I can say I am a GMG man for life. Look forward to many more projects with them, and as far as I am concerned they are the best in the business for quality work, and customer service. Thank you gents."
