New and used 2025 Cadillac OPTIQ SUVs for sale near Denville, NJ

from the beginning of inquiring about the purchase of a new GMC sierra 1500 to the completion of driving one home from John Jonson GMC. This was the best car buying experience I have ever had over the course of 30 years. Both the sales team and financial team were outstanding, friendly, understood what I wanted without also applying any sales or financial pressure during my vehicle purchase. I highly recommend this dealership to anyone looking for a GMC and will be returning when needing another new GMC vehicle in the future. DL

Purchased my xt4 in Dec…had been to two other dealers prior to coming to McGuire . Bob was my salesperson and made the chore of buying the car easy enough. I recently returned there because I had gotten two dings in my doors from lovely parking lot people . The service Dept helped me out there…what a great job on them..removed the dings and really you would never know they were ever. there. Kudos to this dealership.

Rich wax my salesman. Very nice and to the point. Didn’t waste my time, didn’t haggle, worked with me to get a good price. Car was ready to go after I called to make an appointment. Everyone was helpful. Car was cleaned when I came to pick it up. Everything went quick and easy.

Just a wonderful experience at the dealership. Everyone truly cares about any problems you are having with your car. I brought my car in for service. John Ferrari did a great job explaining everything they were gong to do. I have a 2016 ATS and it is now running like a charm. Hats off to a great service department and dealership.

Bob, Sam and Mark made the purchase stress free. It was a pleasure to buy my Cadillac from them. They answered all my questions and were kind and professional. Once I made my decision, the process moved along quickly and smoothly.

Purchased a preowned Escalade from Trinity Cadillac, and the process was very smooth. Confirmed the car was available over the phone, made an appointment to see the car, and it was ready to go when I came in. The sales person was knowledgeable about the features, and the negotiations were pretty smooth. I would recommend this dealer, amd plan on using them again.

Love this dealership, just leased my 3rd car, special thanks to Jason, and Sales guys including Zach, Keith, Shelby, Josh, John Louie and Rich in Finance and the service department. They are professional, and really try to work with you to get you what you want and the best deal! I will never go anywhere else!!

McGuire was a reputable dealer and handled my transaction without incident. Jodie was lovely to work with. I traded my car and they gave me a fair price.

Just pick up our 3rd car from Cad. of Mahwah. As usual no surprises, I am quite happy. My new sales person Ashly really knows her Cadillacs she answered all our questions about the options in a way to easily understand. And also thanks to Paul for all his help and directing me to Ashley.
