Excellent service, quality, and attention to detail. Scotty goes above and beyond every time and is pro-active. Given my car collection, I've tried several shops in Norcal (where I live) and Socal, GMG is the best one. This is why I ship my cars from the Bay Area down south to GMG.

Scotty did an awesome job of taking care of my project. I had all 4 calipers painted with Audi rings added. The work looks awesome and was done timely.

Thanks to Allen and his team at GMG for the best service in the business. I wouldn't take a car anywhere else if I cared anything about it. Great job!

Scott and the team did an excellent job performing a PPI on a potential Porsche. He has a keen eye for detail, carefully looked over the car, and kept me updated along the way. Highly recommend taking your next purchase first to GMG for inspection and expert advice before collection day.
