Scott and the team at GMG were tremendously helpful throughout the entire process. I was very impressed with their product offerings, knowledge of individual vehicle(s) and what best fits with each, and quality of installation. I spent a great deal of time researching competitors and found the breadth of capabilities at GMG to be unmatched.

If you're a discerning customer looking for top flight service, parts and follow through post sale/installation, there's no better place to go than GMG, particularly in southern California. I highly recommend these folks - 10/10 experience.
