My wife and I needed a second family vehicle.
My wife and I needed a second family vehicle. Already having a 2010 Honda Accord which we fully like, that is still running strong with only basic maintenance upkeep all these years. We decided to again look for another Honda because of Honda's excellent well made dependable vehicles that are headache free. We just purchased a new 2025 Honda Pilot Elite through Sales Rep. Deniz Akad at Paragon Honda in Woodside, NY on 5/14/25. Deniz was great. He was very helpful when I worked out pricing with him online and was able to supply us with the exact Pilot trim and color we were looking for. When we came into the Paragon Honda dealership to go through the purchase, Deniz and all his fellow co-workers at the dealership were very professional, helpful and polite. Never felt any pressure during out whole Pilot purchase and made buying a vehicle through Deniz and the whole Paragon Honda dealership a delight! Our two young boys not only like riding around in the new Pilot, which is a great vehicle, but they also bug us for the keys to just sit in it in the driveway. Thank you again Deniz!
Most reliable car I ever drove

Bought a ride from Joseph recently and we were sooo pleased so we decided to come back. He was so helpful the whole way through, and found the perfect car for our daughter. Highly recommend!
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

I’ve traded in cars before, and it’s not always the best
I’ve traded in cars before, and it’s not always the best experience, but this place really impressed me. The process was simple, straightforward, and they gave me an offer that was more than fair. I bought an incredible newer model instead and left super happy! Great experience all around!
Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

A very friendly and honest team .
I brought my BMW X5 from this place I must say my experience with these guys especially Branden was very professional, I found these guys has being trust worthy and very cooperative the went beyond the closing time to make sure I got my vehicle the very day even though I got there around 1& 1/2 hour before closing time ...I got there @ around 6:25 pm and the was supposed to closed @8pm...Thanks to Branden and José ( I hope I got his name right) And finally and most importantly the price that the advertised for their vehicle will be the price you will pay , not like others who will tell you the advertised price is after you pay down 20%..I will definitely recommend North Star Mitsubishi to you.

Steven David Benzel Busch
I rarely write reviews and for the very few times I have done so in my life time, it was always to point out a bad service. HOWEVER. I had exceptional experience purchasing my E400 Coupe with Steven David from Benzel Busch. Since getting my first license back when I was 16, I bought and sold 10 different cars and Steven by far exceeded any of the sales person I have worked in the past. He was very responsive to all of my emails and phone calls. I almost got a reply back within 5 minutes from sending an email and we had many emails back and forth as I was purchasing a vehicle out of state. He was very detailed and truthful when describing a vehicle that I was purchasing. There were few times where he reached out to me first on items normally you wouldn't expect sales person to. Thank you, Hyunbin

Top salesman with a reputable dealership !
I have been purchasing MB automobiles from RVC MB since the 80’s .. I’ve always used the same salesman , Mr Tom Ahrens . Tom has always ensured that my new car purchase goes as smooth as possible .. I’ve always shopped price prior to making the deal - Tom has always beaten the competition prices - a great car coupled with a smooth transaction and a caring salesman working for a reputable dealership works for me !!

The entire dealership staff at CPM was incredibly welcoming, making the process smooth, efficient, and completely hassle-free. I got my Jeep Compass Latitude from them, and the experience exceeded my expectations. If you're looking for a top-tier car-buying experience, I highly recommend CPM and working with Jeremy - he made everything seamless and enjoyable.

I found a great car here at a fair price.
I found a great car here at a fair price. The vehicle itself is fantastic. The only reason I'm giving 4 stars is that I felt a little pressured towards the end to add some extras I wasn't really interested in. However, I stood my ground, and they respected that. Overall, a good purchase.
