The Ingersoll employees provide excellent and friendly service as always whenever I go there for service or to purchase a new car. I highly recommend the dealership.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Lou was my salesperson and he was super communicative,
Lou was my salesperson and he was super communicative, explaining and re-explaining when he seemed to feel it was needed. No surprises along the way, I was able to test drive the van as much or as long as I wanted, have a mechanic come by to inspect it and they washed it and added a full tank of gas on pickup day. They had done some quality servicing to the vehicle as well before pickup day. Lou mentioned early on that he wasn't paid on a commission basis, which was a good detail for me to know. In the end, all the numbers were the same from the beginning to end, no "uh oh" moments and it was a super fast experience on pickup day - probably the fastest ever for me to get the keys and drive a new (to me) vehicle home. I will look to use them again if possible in the next year or so. Highly recommend.

I arrived to be greeted with friendly staff members. My salesman Kamran was great to work with and we were able to work together and get me into a vehicle I am very happy with.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Good vibes
Extremely nice staff, very professional team players from service desk to the shop. A very clean and safely run facility. Waiting area was comfortable. Service was done in a reasonable time. Service prices appear to be fair. Will definitely continue with my service here, also would consider a purchase from them in the future.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

3 years with a loaded 2021Yukon Denali deisel
I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

Excellent customer service during pandemic
We were selling a vehicle. Staff contacted us to give us a link to provide all info for the car we wanted to sell. They gave us an excellent price. ( as evidenced. By kelly blue book ) When bringing car to dealership in East Haven - staff had gloves and masks on. They came outside for paperwork. They were organized. Social distancing followed. We are very please with our experience.

2020 Yukon SLE. Highly recommend!
I previously wrote a review back in 2021 While I was leasing this vehicle. Which still shows up. I just wanted to give an update. I ended up purchasing it after the lease ended. So glad I did. I absolutely love this vehicle. Everything about it. Minus the high back end and price of gas but you're gonna get that with V8 engine. Have had since the spring of 2020. Haven't had any issues at all. Still would highly recommend. Comfort, look, safety, practical, A+ Best vehicle I have ever bought. I would normally have been in a new vehicle by now, I use to upgrade every couple years but not after this purchase, Still very 😊 happy

Great service every time
I bring my fleet vehicle here for repairs/maintenance. Other dealerships have treated me like a second class customer because the fleet company pays for everything. I have never once felt that way at Sullivan's. They are always kind and have gone above and beyond for me at times. My husband became a loyal customer here because of their great customer service.
Yukon Denali all new styling and pleasure to drive
Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Purchased new in October 2024.
Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

Best Car Shopping Expereince!
I just picked up my new car at CarMax of Hartford and, I have to say, this was the best car-buying experience I have ever had. I had found a Ford Explorer that I wanted to see on their lot. I put a hold on the vehicle on their website, very early in the morning. By 9am the same morning, I was contacted by Rocco Toce, the most awesome sales person around. I have bought many vehicles through the years and he is the top of the list! We went to look at the truck and he had it clean and ready for us to test drive. We loved the truck but it just didn’t have all the options that we were looking for. I found the exact Explorer we wanted in New York and Rocco jumped right in to help us transfer the vehicle to Hartford. I have to admit, it IS a leap of faith to pay the transfer fee upfront before even seeing the vehicle in person. Rocco jumped in and took over. He spoke to the other CarMax and had them check every part of the vehicle out. I felt very comfortable after he called and told me the truck sounds good. My Explorer made it to Hartford very quickly and Rocco immediately checked it out and let us know it was perfect! I went to see it yesterday. It was beautiful and in the best shape. Rocco took us through the entire car and never rushed us through anything. He sent our Explorer to detailing while my 2009 Silverado was appraised. I received a fair price for my trade and the deal was smooth and handled professionally by the staff. I’m pretty sure I have not had a better car buying experience. Rocco and the team at Hartford CarMax could not have done more to make our experience the best. I did a ton of research about CarMax like I’m sure everyone does. I drove over an hour to work with them and I am so glad I did. We walked out of there with a great, shiny Ford Explorer and the greatest car buying experience!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.
