READ PLEASE I love my Terrain.
READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

I had an amazing experience at NJ Auto Sales!
I had an amazing experience at NJ Auto Sales! The service was absolutely fantastic from start to finish. A special shoutout to Mina Rizk, he’s hands down the best salesman I’ve ever worked with. He was knowledgeable, honest, and really took the time to understand what I was looking for. Mina made the entire process smooth and stress-free. If you’re looking for a great deal and top-notch service, ask for Mina. He’s the guy you want on your side!

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! 🚗💯
