Excellent and honest mechanic at fair prices. Gary has serviced all of my cars from new to muscle car to antique. Best in the Central NJ area. - John L. (5 star review on Google)

Top independent service and repair. Dependable, competent, and honest. - David G. (5 star review on Google)

Gary is great; he explains things in a language that a non-car person can understand. I trust him to take good and honest care of my daily driver and with my baby, a 1965 Mustang! - Cathi P. (5 star review on Google)

GC Automotive is honest, reliable, and do quality work at a reasonable cost; they only do the work that is required. I'm very pleased with the repairs that they have done on my Nissan Maxima. GC was recommended by my neighbor, and I would recommend them to anyone who needs repairs or service on their vehicle. - Hanna L. (5 star review on Google)

First of all, I would like to say I have been using GC Auto for several years & have recommended several of my friends and neighbors. Over the years I have found Gary to be honest & reasonably priced. In that business it is not always easy to find. He will tell you if you need to do something immediately or you can wait. Again that speaks for itself about his integrity. - Howard L. (5 star review on Google)

Had an odd problem with the computer in my car and other shops couldn't seem to narrow down, but Gary and the guys solved the problem right away for a next to nothing!  - Kevin K. (5 star review on Google)

I have been using GC Auto Performance for over 4 years now. Gary is the only person i let work on any of my cars. He is honest and an expert on automotive repairs and modifications. I have never taken a vehicle back for the same issue. Once its fixed its fixed. Also you dont fix one thing and have another break like some mechanics. He has never pushed me to do unnecessary work on my cars and has talked me out of more expensive options just because he felt it was not needed. I cant say enough good things abut Gary and his crew at GC auto performance. I have a 2010 Mustang GT that he has completely modified for me along with my regular service on all my other vehicles. I have recommended GC to friends and family with no regrets.  - John E. (5 star review on Google)
