Danny and the team did an outstanding job installing my new sound system. Danny was knowledgeable, took the time to explain everything, and made several great recommendations that really improved the final result. I also appreciate supporting a company that’s committed to giving back to the community through its outreach programs for local first responders, veterans, and individuals facing hardships. They had some really impressive projects in their shop when I stopped by, and it’s clear they take pride in their work.Posted on Google![]()

I’ve now trusted Top Edge with my 2007 BMW 328i through several repairs over the past few years, and they’ve consistently delivered quality work and honest service. Whether it was tracking down a coolant leak, replacing the radiator, or earlier maintenance, they’ve always taken the time to explain my options and communicate throughout the repair process. I never feel pressured into unnecessary work, and that’s why I continue to recommend them. It’s hard to find an independent shop that’s knowledgeable, trustworthy, and stands behind its work.Posted on Google![]()

I recently had Top Edge Automotive Specialists install a front and rear dash cam in my new 2027 Kia Telluride, and the experience was great from start to finish. The team was professional, polite, courteous, and took the time to answer all of my questions. The installation was flawless—every wire was neatly tucked away for a clean, factory-like appearance, and they configured the system to ensure the parking mode works properly without unnecessarily draining the battery. Their attention to detail and commitment to quality really stood out. I highly recommend Top Edge Automotive Specialists to anyone looking for a professional dash cam installation or other automotive electronics work. I'll definitely return for future services.Posted on Google![]()
