Always great customer service.
Always great customer service. Excellent waiting area with fresh coffee and a good choice of goodies while you wait! I love the new computer system showing your car while you wait
So far so good!
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.

2020 GMC 2500 AT4
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.

Best truck I have owned
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.

Awesome Salesman and Great Price
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!

Excellent dealer
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!

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 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.

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.
Never had one. Always wanted one and love it.
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.
