We have worked through Frampton Walker for at least 5 GMC vehicles. He is our first call every time we need a new car or have an issue that needs to be addressed because of his professionalism, attention to detail, and he solves our problem.

GREAT GUYS AND SOME COOL CARS
I'm a car nut and these guys seem to be the same. I visited their lot and they have a great range of cars for all budgets. If you are someone on a tight budget but looking to get a lot for your money I would highly recommend Vision.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

My experience with purchasing a car at Nielsen Ford in
My experience with purchasing a car at Nielsen Ford in Morristown was excellent! After seeing an advertisement on Facebook for a 2024 Ford Edge Titanium SUV, I stopped by the dealership and Orhun Varol was the salesman who helped me. From the Test Drive to the negotiating selling my current car to Nielsen Ford, Mr. Varol kept things going smoothly. He took the time to answer all my questions. I drove out of the dealership a few hours later in my new car, thanks to my excellent salesman Ohrun Varol. A+++

The customer service was great and they were welcoming
The customer service was great and they were welcoming and helpful as soon as I came into the dealership. It was the first time taking my car in for routine service and the receptionist was so helpful of completing the paper work and answered all my questions. I purchased the car from this dealership in October. I had the best sales person and the finance person was so good and they both made the buying process perfect.

The salesman, Johnny Brown, was very personable.
The salesman, Johnny Brown, was very personable. He didn't pressure us to do anything which was refreshing. The dealership, however, added approximately $4,000 to the price for miscellaneous fees (not including tax) which if very high in my opinion. We were able to come to an agreement, but feel we maybe should have paid a little less. The care needed a small touchup in two places and an A was missing from elantra . Still waiting for the "a" to arrive as well as touch-up paint.

Great experience!
Great experience! Our sales rep Michael V. was incredible and made the process of purchasing a car as easy as possible! He also followed up to ensure if we had any questions or issues after purchasing vehicle. Finance department, Rich, was great, explained the all the paperwork and I never felt pushed into purchasing any extra add ons. I would definitely recommend this dealership!

Island Auto Group is the place for 🚗 Let me share my
Island Auto Group is the place for 🚗 Let me share my first car buying experience in New York. As someone with zero prior knowledge of how dealerships work, it was incredibly challenging and stressful at first. For over a month, I hunted for a reliable, low-mileage car with excellent safety features, low maintenance, and something within my budget. I ultimately decided between a Subaru Crosstrek or Mazda CX-5. I checked online sites like Cars.com, Carfax, and CarGurus, visited around 10 dealerships (both independent lots and franchises), made tons of phone calls, and even explored Carvana and CarMax. Too many places baited me with low online prices, only to pile on thousands in hidden fees once I showed up—things like mandatory down payments, wear-and-tear charges, inspection fees, and dealership add-ons. But from this experience, I learned a lot about how dealerships really work and gained some valuable knowledge: never fully trust the prices posted online without confirming the true out-the-door cost in person. After five frustrating in-person visits, I was ready to give up on traditional dealerships and just overpay at CarMax to avoid the headaches. That’s when I spotted a listing on Cars.com from Island Subaru. The vehicle photos clearly stated “No hidden fees, no extra fees – fully transparent OTD price.” Skeptical after so many bad experiences, I decided to try one last time and walked in without an appointment or even a phone call. Right away, I met sales representative Christopher Chavous (everyone calls him Chris). He was patient, professional, and didn’t bombard me with unnecessary questions or personal info. He showed me the Crosstrek I was interested in, sat with me for two detailed test drives, and explained all the features thoroughly. The standout moment? Chris gave me the true out-the-door price immediately—no games, no surprises, exactly matching the online listing with zero hidden fees. In an industry full of tricks, this level of honesty instantly built trust, which is everything when buying a car. After some fair negotiation, the manager approved a solid discount, and we sealed the deal that same day. Since it was Saturday and close to closing (they couldn’t finish the NY inspection), they went the extra mile and loaned me a brand-new Subaru Crosstrek to drive until Monday when my car was ready. Finance manager Yuri Miyakawa handled the paperwork smoothly, got me a great rate, and made everything straightforward. But Chris truly went above and beyond—he guided me through the entire purchase process and even helped set up my first car insurance. The initial quotes were sky-high for a new driver, but Chris personally called the insurance company, advocated on my behalf, and somehow got my rate reduced to half the original quote! That kind of dedication is rare. The whole team—the manager, Yuri, Chris, and the rest of the staff—was genuinely helpful and made me feel valued. I drove home in my Certified Pre-Owned Subaru Crosstrek Limited with just 9k miles, at the exact negotiated price, with all documents perfect, a full tank of gas, a fresh car wash, and three free oil changes for the first year. Island Subaru transformed a potentially nightmare first-time buying experience into something positive and memorable. Their transparency, honesty, and outstanding customer service set them apart. I’ll definitely recommend them to friends and family, and I’ll be back for my next car. Thank you, Island Subaru team—especially Chris for your incredible support throughout! 🚗💯
