PETER FEARON at Helms Bro
PETER FEARON. Ever had that stabbing dread of entering a Car Dealership due to the sudden urge of adrenaline coursing through your veins - your body's way of preparing for the inevitable/unavoidable funky sales tactics, mind games performed by shady Car Salesmen? Well, NOT with Peter Fearson at Helms Bro. I was very fortunate that my brother had introduced me to Peter Fearon who sold him a car three years ago. (If this example of repeat business wasn't enough for you then continue to read on). Upon being introduced to Peter Fearon, all of my nerves seemed to subside, as you can immediately tell, Peter is not one of those "shady" car salesmen. His utmost professional behavior is coupled by the reassurance of his humor, kind, and non-aggressive approach. Peter advised me of ALL the solutions possible to help me get rid of my lease by letting my brother and me make our own decision. He tirelessly worked on making sure the numbers made me HAPPY. I honestly felt that he was looking out for my best interest and that's all that really matters - an act of Altruism that is easy by definition, but difficult to execute. I really hope that you choose Peter Fearon to help guide you in your next choice of vehicle. You wont regret it.

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

A totally positive experience
I had a positive experience at this Mercedes Benz dealership. This is the 2nd time I have leased a vehicle from them. Henri Sabar assisted me and did a phenomenal job. He was very professional and explained everything to me along the way. Joe helped me with the financing aspect of the process and he did a great job as well.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Excellent purchasing experience at MB of Hunt.
We were in the very capable hands of Anthony Mastroianni, who expertly guided us through the process of purchasing our car. Anthony was extremely professional, very knowledgeable, thorough, and of course patient. He was very attentive and made every effort to answer all our questions and concerns during this process. Additionally, touring the Huntington facility reassured us that we would be in good hands on all our subsequent service visits. We continue to be most pleased with our recent car purchase and would highly recommend our sales consultant, Anthony Mastroianni, to guide potential buyers through this exciting process. Thank you Anthony!

Great Experience!
I had reached out to several car dealers regarding Mercedes and BMWs and Rodni was the first to respond. Even though I live in Central NJ, his prompt response was impressive so I went out to this dealership a few days later. I wound up purchasing a beautiful Mercedes and I'm very pleased with my dealership experience.

Tom Aveni is a pleasure to work with
Tom Aveni is a pleasure to work with. We live in northern VA. He was so responsive to our needs that I took the Acela train and Long Island Rail to get to Huntington, NY and bought a GLC300 from him. Great experience all around. And even after a couple of months he still reaches out to make sure everything is good. He also ordered a part that was hard to find and kept me informed until it was found and shipped. He cares and he follows through.He is now my go to advisor for all our Mercedes needs.

Amazing Service!
I went to Helms for my birthday to get myself a birthday gift where I was assisted by Maurice Martin who was so pleasant, patient, informative and super helpful. I've actually never had such great customer service in my life. I purchased my dream car, a white C300 4MATIC and I couldn't be any more happier with the service and help that I was given. I couldn't thank Maurice enough, he was such an amazing sales person. I also worked with Reggie when it was time to deal with the financial part of the process and he was very pleasant, helpful and informative as well. Not to mention, the atmosphere was also extremely pleasant and clean. Everyone who worked there that I came across was very nice and welcoming. I advise you to visit Helms Bros in Bayside if you're looking for a new ride. These people are awesome!

We just purchased a car from this dealership, and the experience was night and day compared to our prior one at another Mercedes dealer. The team here is incredibly friendly, down-to-earth, and easygoing—such a refreshing change! Albert is the one who helped us, and he truly went above and beyond. He was patient, helpful, and never pushy. He even took the extra steps to help us clean out our old car, remove the old box and items, and made sure everything was taken care of. It was such a smooth and relaxed experience—nothing like the stressful process we had at the other dealership. Highly recommend working with Albert if you’re looking for a great car-buying experience!
