I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Jonathan C hizo un buen trabajo, me ayudó bastante y le recomiendo a cualquier persona.

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

My guy Victor had me in and out in no time excellent experience! Go there

I live in the Indianapolis area and found the SUV my family was needing. I talked to Shawn and told him I wanted an honest description of the vehicle before I drove 5 hours to purchase it. When we got their it was exactly what he described. I would definitely buy from Shawn again!

Service Department always comes through. Iblike to wait and Keith gave me almost to the minute my wait time. And thank you for washing my jeep. A real plus

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

I just bought a new Bronco Raptor from Brewster Ford and it was a 5 start experience, my sales manager Michael Rose did all the process nice and smooth, I will definitely go back in the near future for another cars.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

My wife's car was about 6 months away from end of lease and she decided that she drives too many miles and would like to buy her next car. So we decided to start looking. We first went back to our Mazda dealer and told them we were looking for a used car and gave our budget. We were basically told they didn't have any used vehicles (really?), and that we should wait and see if any promos run. I used to drive Altimas (I had 3 - last one in 2010) so I suggested she look at that car and we went to Rockland Nissan. We were immediately greeting by Michael, new to Nissan, but very nice and professional. After discussing what we wanted and that we didn't think we could get one right now, he looked at inventory andour budget, and found us a car we could get. So we agreed and filled out the paperwork - the only real hiccup was when we spoke to their finance manager - the monthly fee was higher than we were promised. The issue was my wife was over in miles on her lease so Tim O'keefe (the main guy there) came in, sat with us and in no time we had a deal at a price we were happy with.We got a 2017 Altima 3.5 SL with only about 35k miles for a very fair price. My wife LOVES the car and we couldn't be happier. Fast forward to the next day - she noticed some damage on the front bumper that wasn't disclosed. Perhaps no one noticed, but we took it back and without a thought, they agreed to fix it for free. Now I was so impressed with Tim that I told him (jokingly) I have about a year on my Mazda 6 and I'd love to get a new Altima. He asked me to come in the next day and he'd find a way to get me what I wanted at the price I was comfortable with. So i showed up early in the morning and Tim introduced me to Dave. A very experienced and excellent sales person - one of the best I've met in the industry. He was honest and patient and we went over everything I wanted. He showed me a few models and I fell in love with the 2019 Altima SL in Storm Blue (really nice color - looks almost black). We went back over to Tim and before I knew it, we had a deal. The only negative thing is I was there for six hours before I left with the car. They were very busy and I believe a bit understaffed. I have to say though, I LOVE this car and could not be happier with how I felt taken care of. This dealership treated me like I was their top priority (except when I had to wait for a while) and the overall experience was fantastic. 2 days - 2 Altimas. I'll be going back there for sure. Thanks to Tim, Dave, Michael, and the rest of the Rockland Nissan team!

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Amazing service team, tech kept vehicle clean and service Consultant kept me up to date on my needed services and repair, pricing is affordable and fair

You have the NICEST people working there! Cordial, professional, and extremely helpful. 10 STAR STAFF!! Now let's talk about your coffee...lol...sorry can only give the 2 stars!!!! lol

Victor was super nice and professional and patient. Knew much about the vehicle and its history and had maintenance documents ready to give me along with carfax. He also have the vehicle washed before my visit. He was very prepared. I did not buy on that day but I’m hoping to return should they agree to be flexible on their pricing. Seems like a well run dealership.

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Luis was a prepared, kind, and cordial associate who I had the pleasure of working with. After some honest negotiation and a little bit of elbow grease, he got me to my number. My Dodge Hornet has been great! He made buying this car a breeze and was very responsive over email as a pre-vetting process.

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

We are happy with the staff and clean environment. Lucas and Rob was really helpful with the purchase.

Peter is a kind person and wonderful salesman. He is a credit to Ingersoll Auto Group! He helped make our lease go smoothly and efficiently. This is our second time we have worked with Peter to lease a new car, and he directs us to the perfect car for our needs.

Great experience and chemistry Joseph Etcheto was just flat out fantastic He made sure the car I wanted was available and worked on my time to make sure I was happy with this decision

Great dealer with some of the best selection of vehicles kept indoors I’ve come across. The staff is all very friendly and helpful and they helped me get the exact car that I wanted all in the same day!

First , I bought gas 6.0 , the diesels are great if you have serious towing needs. You just need to realize no matter how well you maintain a diesel it will at some point have an expensive repair. I've had my truck about 12 years. Regular maintenance , a few batteries , couple sets of tires and a MAF sensor. I tow a couple different trailers and the heaviest is less than 10k loaded. Towing , zero issues , no band aids , no overloads , no equalizing hitch , no sway control. Simply not needed. Drives amazing, stops great, Roughly 10 to 12 MPG towing. Unloaded driving at 60 / 65 on cruise solid 15 to 16 MPG. Yes , it won't pul the hills like a diesel but thats a small price to pay for an absolutely amazing truck. I want a new truck in the worst way but just can't part with this truck. A very good truck if you find a clean well maintained one.
