I refer to myself as Big John. I went to Cal State Fullerton and started in the automotive industry in 1987. I began working at Jim Curley GMC IN 2022. I truly love the car business and consider my co-workers my friends. They are the heart of the dealership. I am originally from Linden, N.J. and have lived in Toms Rivers since 1997 .I lived in California for 6 1/2 years, and my first real job was at Disneyland. That is where I learned that customers always come first. I've been married to my wife Barbara since 1992 and have twins Nick and Kaitlyn. Both college grads and both enrolled getting their masters in education and business analytics. . I'm proud to say that my wife and my kids are everything to me . My success is their success . It feels great to be with the Curley family . Now 2 great locations! Jim Curley Buick GMC of Lakewood, NJ Jim Curley GMC of Keyport , NJ

I would highly recommend Cynthia to my family and

I would highly recommend Cynthia to my family and friends. After 5 years we were having trouble with our gps, we went to the dealership to have the Buick oiled and greased, my husband saw Cynthia and she asked how things were going and my husband told her about the gps. She then said let me take a look and one half hour later she had it all fixed. (Mindful she was on her way home) Where are you going to find caring people like Cynthia and the rest of the Jim Curley team.
