Just as promised. A great used car deal!
Saw vehicle on the internet on a Sunday. Called and AMY answered. Based on her accurate information she invited us to the lot the same day. We drove 2.5 hours and test drove the Honda CR-Z. AMY made sure all of our questions were answered. The car was an excellent deal for the price offered. The car did need brakes and a light. AMY made sure the repairs were done to perfection. She communicated via text over the next few days. Always answered instantly. The car was ready when they said it was. Everything completed as promised. Paperwork was painless. By Wednesday evening I was home with the car! AMY was a professional, the business did what they said. No Gimmicks, no false promises, no issues!
2019 Canyon Denali.
2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

Old lady in need of a vehicle!
Today, purchased the 2013 Nissan Juke, 112,600 mile for $9,995 today. It will be ready Wednesday or Thursday this coming week. My sales person Amy was excellent. She knew I had a firm budget (retired) and she found two great vehicles to test. The Jeep I could have taken home today with less milage... a little older, however, Jeep mph versus the Juke..., Nissan won even with higher mileage. So far, I'm "a HAPPY CAMPER"! I can't foresee any problems from now until pick-up. So, I'd say, if you need a reliable used car, Amy is knowledgeable and, in spite of the packed waiting room with eager customers, we were never abandoned. Note; yes, the sales people had to multi-task at times. Understand, at these reduced prices, compared to any dealerships for used cars... Patience, just a little patience - and you'll be treated right too. All the best to customers in need of a new used vehicle!

a place to go for bargains if you have patience
Alex excellent salesperson very patience and honest. The dealership is another story, if your looking for a reasonable price this is the dealership for you, they get cars from Auction so no idea about the history of the car, they get checked when you already signed for the As- is purchase, don't go there on a weekend, if you have patience, wants a bargain, (non negotiable deals)time, and good mechanic this is a place to go, got lucky with Alex very accommodating and great salesman

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Overall it was a good experience!
Overall it was a good experience! I had no issues during the process as everything ran smoothly.
Bought the car CPO in summer 2021 with 38k miles.
Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

Fast and dirty.
Fast and dirty. 20+ salesmen all busy. 800 used cars from auction, none of them have been detailed yet. If you need a car today on a sub $15k budget I would go here and detail it yourself. Good place to buy a first car. Don’t buy a luxury item or anything collectible. The the inventory doesn’t turn super fast so every single car will likely need a rotor resurfacing. They had family guy on the tv which I thought was odd for a dealership. Not really dealership vibes, which is good!
My Work horse.
I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Love Our New 2023 Denali Terrain!
We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Great Service Department
In maintaining our 2020 Buick Enclave, we have used Buick GMC Watertown Ct, since our purchase in September 2019 and have always received the best on time, reliable service and friendly customer service on our visits. The staff that reviews what service I am requesting will always review for possible upcoming recommendations of service as well. The cost and approximate time of completion has always been spot on.
Ridiculously fast
Bought 2013 SLE 4cyl Terrain used and a year old in 2014. It's 2022 and it has 35,000 miles on it This little truck is like a race car. Had to replace the transmission. It blew up as I left getting it inspected. Pretty stupid that it's impossible to check Trans fluid . whos dumb idea was that? Signals come,on randomly. Tires are difficult to find 235/60/17 101.. This Little SUV is ridiculously fast for a 4 cyl 4 banger!!

Fixed everything I said to after test drive
From the moment i went in to test drive a vehicle to the moment i drove away in an immaculately detailed used Mercedes, the staff gave me no issues or pressure of any sort. Just smiles- Carlos is the financer and salesperson and by the time i left i felt like we had become friends. He was even able to save me $500 off the total sales price. I would recommend them- they were honest and me the car buying process easy
Would buy again!
Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

Excellent buying experience!
My family drove two hours from RI to buy our new GMC truck at Ingersoll. The price was excellent and the service was outstanding. Kyle, the GM of the dealership greets you when you arrive and even puts the temporary plate on your vehicle. Truly an outstanding experience. 👌🏼

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

Addendum to Terrible service.! Terrible car!
I previously left Executive Chevy a terrible review; I should note that the advisor who dropped the ball was NOT Steve in the Service Dept. He's actually right now trying to resolve this issue, which was unbeknownst to me. I believe in calling "xxxxx and strikes", and Steve is making an attempt to resolve which at this point is all we can ask for, as the previous Service Advisor did nothing. Understand there's a lot of red tape for him to deal with and we're keeping our fingers crossed he can work something out. I normally don't like to have to "MF" a business, but it was warranted because of past advisor ineptitude. Still not completely sold on Chevy's, but if Steve comes through it'll restore my faith in USA cars which I love, especially Chevy trucks.
Beautiful truck
Vehicle is very nice and has all the bells and whistles. I bought it to pull a 26 ft Airstream and it does the job but not great, could use more power for towing. It is difficult now to find a vehicle to pull a large trailer. I didn't want a pickup because I haul a large dog that takes up the entire back seat. I wish they still made the 3 quarter ton Yukon with the larger motor like I used to have. You could haul anything with it. The Yukon XL with the 6.2 motor just barely does the job.

Wallingford Auto Park: Best Place To it A Car
Excellent dealership. I worked with Phil and bought a Nissan Rogue. Phil is the best salesman I have worked with. He made the whole buying experience so easy and stress free. I’m so happy with my purchase. My entire experience was top notch. Thank you Joe and Marcelo also. You guys are great!!
Good collection of car
Friendly staff, great price for the car. There was a far bit of waiting around but with the volume of cars they are shifting on a daily basis, it was kind of expected. From the very short test drive to driving out with my car was around 45 minutes.Would definitely use then again.

Love love LOVE
I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

Great experience. Tyler was fantastic to work with, the whole thing was completed quickly and we left very satisfied!
Gas and diesel terrain
I have owned 5 of the 2018-19 terrains. I have had the 1.5 gas, 2.0 gas and the 1.6 diesel. The power on the 2.0 is awesome. Mileage on the 1.5 is good. Mileage on the 1.6 diesel is great. I have 336,000 miles on my diesel. It has had lots of issues due to emissions and transmissions. Last week it got a new engine as well. The car is a great car but I would recommend the 1.5 gas for most people. The terrain is comfortable and makes a great work or travel vehicle. Size is easy to park with plenty of leg room.
