Sansone Hyundai did the right thing.
Sansone Hyundai did the right thing. My son and I purchase a certified pre-owned 2022 Hyundai Tuscan on July 15,2024. During the courtesy oil and filter change in January 2024, the service technician indicated that all four tires needed to be replaced. Instead of reacting, a second opinion was sought that confirmed the tire tread was deteriorating or wearing. Noting that the vehicle mileages at purchase was approx. 23,000 miles and had approx. 27,600 miles in January, plus quality tires should last 50,000 to 60,000 miles assuming normal driving conditions, the tire condition seemed abnormal. Another fact was the second opinion revealed the tire’s manufacturing date in 2020, which also does not seem proper. Upon contacting Sales Manager, Operations Manager and Service, another set of tires were installed and aligned at no cost.
This truck has a jerk when changing gears sometimes.

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+++

I had an excellent experience at Fast Track Motors.
I had an excellent experience at Fast Track Motors. From the moment I walked in, the staff was friendly, knowledgeable, and genuinely helpful. They took the time to understand what I was looking for and helped me find a vehicle that fit my needs and budget perfectly. The buying process was smooth, transparent, and pressure-free. I appreciated how clearly everything was explained, and there were no hidden fees or surprises. The vehicle I purchased was in great condition, clean, and exactly as advertised. What really stood out was their customer service—responsive, professional, and honest. Even after the sale, they followed up to ensure I was happy with my purchase and answered any questions I had. I highly recommend Fast Track Motors to anyone looking for a quality vehicle and a dealership that truly cares about its customers. I’ll definitely be returning for future purchases!

I recently had the pleasure of trading in and purchasing
I recently had the pleasure of trading in and purchasing my 2nd vehicle in 3 years from George Gregory at Sawyer Lyons GMC. Every time I visit this dealership (for service or sales), I feel welcomed and valued. George, who has always been both friendly and professional, always takes the time to say hello and that leaves a lasting impression on customers During the sales process, he has never pressured me into making a decision but instead encouraged me to take my time and ask questions. What really stood out, though, was his commitment to ensuring I got the best deal possible. He worked with the finance team to offer competitive pricing and tailored options that fit my budget. Throughout the negotiation, he was transparent, honest, and made sure I was comfortable with every step. Because of my experience with George, I feel confident in my purchase, not just because of the great car I was driving off with, but because of the exceptional service I received. It's rare to find a car salesman who genuinely prioritizes customer satisfaction over making a sale, but this one certainly did. If you're in the market for a new vehicle, I highly recommend working with him—his professionalism and customer-first attitude made all the difference.

I’ve leased vehicles for many years.
I’ve leased vehicles for many years. I have to say my experience with Ali Bayat @ Mahwah Honda was the best experience dealing with any automobile sales person, there was no haggling and back and forth. He said he would get me in my price range & delivered ! and we all know that is a special gift in today’s car leasing business today. That being said the SUV I leased is a quality vehicle. & if you’re in the market for a Honda, & want to have a quality experience with a sales person Ali Bayat @ Mahwah Honda is your person …. Thank you Ali

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! 🚗💯
