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

John was the sales advisor when my daughter was looking for a used truck and my daughter is so pleased with her truck. Straight away John was totally up front and transparent with pricing with a no nons for a used truck and my daughter is so pleased with her truck. Straight away John was totally up front and transparent with pricing with a no nonsense structure to it. We really felt comfortable working with them, and wouldn't hesitate in recommending them to others. We didn't go with their financing as we had our own lined up, and I know that can be an extra revenue stream when buying a car, but the team at Jim Curley did not make it an issue at all and were more than happy to work with us. All in all a seamless and enjoyable process which resulted in one happy girl. So again our sincerest thanks to the sales team at Jim Curley. And we will definitely keep you in mind for future purchases. More
