Our Reviews

It was a great experience! Thanks to Noah it all went smoothly we were in and out, in no time! Noah was very knowledgeable about the various vehicles we looked at and it was helpful in making our decision! Thank you Noah!!

Excellent

My car was towed there and sat 7 days before it was even looked at.it was determined it was the battery which was fixed on day 8. Total cost $571!! $354 for battery $198 labor Added tax Bought the car at this dealership but was informed I was not a preferred customer. Now I won’t be a customer at all!

Very friendly and professional service, all at the service desk were very accommodating as I came in (with my pup who they were also very friendly to) and signed me in, I was able to get a ride to my office and was called as agreed when the truck service was completed. I jhaven't had any bad experience with the Service Department in all of the years I have done business with them.

Our buying experience was easy and stress free. One of the best we have ever had. Greg A did an amazing job understanding our needs as a client and met them 100%.

Everything went well

Salesperson was very patient , took the time to make sure I was comfortable with all of the accessories , finance was great, was ready when we arrived, sales manager very helpful, was very happy from test drive to delivery

Very pleasant atmosphere very professional and kind people great service work done in short period of time makes your car is in good shape and ready for the road

Great experience! Horacio was so nice and helpful! So happy with my csr

Work was performed well.

****ario D'Addario GMC is the BEST! On my fifth vehicle with the D'Addario family (GMC and Nissan) and never disappointed with the great care from sales, maintenance and most recently the collision center. As I navigated a recent insurance claim due to falling tree damage to my GMC Sierra, at my request the collision center provided an on the spot (and unscheduled) estimate, opened a work order, and ordered parts even before my insurance company initiated their claim. This expedited my repairs and returned my vehicle ahead of schedule to support my schedule. Thank you Bob Graf and the entire staff at the collision center for the great care and service!

Fantastic experience from the 1st phone call to the actual purchase! 5 days!! Love my new Yukon AT4!

Excellent customer service.

Service department is excellent I never had a problem with setting up a appointment and with the work the mechanics do I would highly recommend them

Michelle was awesome in service

Service was excellent Will recommend!

Staff wad friendly and professional. Explained what to expect and kept me informed

Everything was terrific. I'll definitely be back.

Date of service was 12/19/25. Oil change and TPMS changed on three tires. Price for sensors higher than expected as referred to online.

Pain less quick and smooth threw the process.

My visit for an oil change at D'Addario Buick GMC was great! The people there are always friendly and efficient. I have taken my GMC there for oil changes since it was new and will continue to do so because I feel they have first class customer service.

Very professional and knowledgeable. Whole experience and people were great and made everything very easy

Bought a new truck Greg and everything went smooth. Greg was an excellent person to work with.

excellent service

Great job

Professional and completely satisfied in every way! Excellent!

👍

Saturdays are busy times-needed new battery and did take a while-but service guy did keep me informed!

Everyone was very wonderful taking there time with me and not being pushy!! I enjoyed working with everyone and I would like to come back in the future

The service was much better this time with with the time allotment given at the desk for completion,

Michelle in service is excellent. Can’t say enough good things about her thank you.

Perfect

As always, Michelle was friendly, professional, and helpful. I was a bit disappointed with GMC however. My Canyon has only 9800 miles and the second oil change was supposed to be part of the new car coverage. Was told that it expired August 31st. Thought good business would be to offer the service without charge as I am a long term customer currently servicing two Canyons. It was the principle of the issue more than the cost.

DJ and Rosemary holding down the fort! Give them both a raise!!

My salesman, Tyrell Walker, said the financial person that I worked with, were awesome. I was working with four different dealerships in search of the vehicle I bought, and by far they were great to work with and helped get me in the vehicle I wanted. Thank you!!

I walked into your dealership with high doubts of recieving a car .. I had dub par credit due to unfortunate circumstances !! I walked out with brand new terrain thanks to Noah and Jim working their magic !! Look forward to future with Gm !! Inwill absolutely spread the word !!!

The service I received was ok. I was not happy with the fact that when I dropped my vehicle off at 11am it hadn't been looked at at 4p when I received an update. On the second day, it was finally looked at where a new muffler needed to be installed but the muffler want onsite and needed to be ordered. By the third day, I finally had my vehicle back. I understand that sometimes the service center can get busy and, as a result,things can take longer. But if I have an appointment, my vehicle should be looked at the first day that it's there. The staff is typically friendly and I haven't had any issues with repairs being performed poorly so far.

Friendly, easy and efficient

Excellent dealership

The salesman and financial officer were courteous and efficient.

Everyone that I was in contact was very pleasant.

Excellent service and attention. Noah and Sean were awesome

I was very upset with my last service visit. I routinely take my vehicle into dealership. I was there 6 weeks prior and had a transmission flush and asked if anything was needed I was assured everything is up to date. Then 2 weeks ago my car started driving irregularly, so I brought it in for service and my transfer case needed to be replaced because there was zero oil in it. I asked how this could happen? They never ever mentioned or said it needed to be replaced. I asked to get some clarification from the service manager were he totally dismissed me. I explained that I was a very loyal customer and also have been leasing cars from sister brand Nissan for 20 years is there anything he could do for me? He said we took $800 off the price of Job. I asked him to show me on receipt that in fact is was discounted. He said I didn't put on paperwork we just did it. I don't think that's how a loyal customer should be treated.

Great

We called from another state, hoping to make a deal and get a good price. Horacio was able to work with us over the phone and we were able to come to an agreement. We drove there and in the next few hours we had a brand new vehicle. Jim from the finance section was a pleasure to work with as well.

Steve was excellent and very helpful, my vehicle looks great!

Salesman was great and answered all of my questions

Very friendly dealership

Excellent experience, sales process was smooth and vehicle delivery was very efficient.

Brought in our 2025 Yukon XL for the first oil change as in the past simple process.

Very friendly and professional service.

Great customer service team

all work done correctly and on time. pleasant experience. see you at 10,000 miles!!!

On time, professional service and pleasant, dedicated personnel.

Everyone was extremely polite and the service was great

Very professional. Easy to work with. Got the deal I wanted. What more could you ask for.

Exceptional customer service. Great communication.

Very pleasant to have my Buick Envista serviced at the D'Addario dealership. Easy to make the appointment, treated like a V.I.P. on arrival, comfortable waiting area with coffee and snacks, fair price for full service and tire rotation. Well pleased!

It was quick and easy. You delivered everything that I expected.

I recently had a service appt, was told by staff when booking appt the appt would’ve 45 minutes and I did not need to arrange transportation as the sensor replacement would be very fast. On the contrary, I was there for over 3.5 hours with minimal communication about the status. It was an inconvenience and a poor experience.

I was due for an oil change, but noticed an oil leak, burnt oil smell and staining on garage floor. I was apprehensive as to the problem and anticipated the worst. Diagnosis...small hole in oil filter, and regular oil change service fixed it all.

Great work expensive price however

The service department is awesome. From setting up the appointment to the staff in the department. Dillon kept me updated throughout the process while I waited. I actually bought my Buick in 2021 because of the service department!!!

Great communication quicks making an appointment everyone very kind this is why I keep coming back wish I purchased with you guys in the first place

I had a great experience with Horacio and Jim - both were wonderful in helping me get my car.

The Staff is excellent and very courteous. They answered any question i had and made the process very smooth.

I was helped by Michelle who was very pleasant and helpful.

Everyone was very helpful

They were very helpful!

Great experience. Top notch staff!!

My experience at Mario D’ADDARIO‘s service department was amazing. I was greeted by a very friendly young man. He showed me to the waiting area explained there was coffee. The ladies room was around the corner and they would be pretty sure they’d be finished with my car within about an hour if I needed anything, just simply ask the place was very clean. There was a nice television to listen to or see and in general it was a very, very pleasant experience.

taken in quickly very smooth

Ripped off money wise

Always great to work with

I am always treated with respect and feel welcome. Everything was dealt with and I was given what needed to be done in the future. Thank you for the wonderful service. Have a good day!

It was all good

great service, great people

The entire team did a terrific job!

Nice inventory to choose from and sales people were great

Very satisfied

Horacio and Jim were easy to work with and flawless

fast response to my problem with a timely solution

Dillon the Mgr and Customer Service absolutely Fantastic! 😊

The staff were very professional and helpful. The job was performed well, to my knowledge, The facilities are quite nice. The job took too long. An oil change should take no more than 30 minutes. Running a car through the car wash after that should take way less than an additional 30 minutes. To change the oil in my truck and get it washed took nearly two and a half hours. This could stand to be improved. Hope this helps.

It was a great experience, the sales team at D’addario are top notch.

Everyone was pleasant, knowledgeable and extremely helpful. Would recommend this dealership to my friends and family

My appointment was for 10:00 am & due to predictions of bad weather beginning around that time I called Michelle Chonko, Service Consultant to see if they could take me sooner, as being 82yrs old, she was so gracious to get me in half hour earlier & greeted me so warmly as she has always done in the past! And the girl whom I paid my bill to (forgot her name) was also so kind & pleasant! Both young ladies very professional & also so friendly & polite!

Never an issue, dealership always accommodating, pleasant personal, good service.

The automated phone system worked great due to the fact that it let me leave a voicemail after booking an appointment. Michelle contacted me immediately and got me in same day. Worked out perfectly

Very helpful and courteous. Very nice and clean job!

Excellent customer service and inviting waiting room.

It was a long day. When we finished, we had covered many bases and completed the transaction. The upgrade to 2026 Sierra 1500 Denali was worth the effort.! ajD 2/19/26

Excellent Customer Service! Everyone very professional and friendly! Thank-you Dillion! and Thank-you to the person who called to remind us. 😊👍🏻

Friendly and informative staff

Great service

Great experience with Buick! The team was professional, friendly, and made the whole process smooth and stress-free. They explained everything clearly and treated me with respect. Very happy with my new Buick and the excellent service. Highly recommend!

Okay

They put a Tonneau cover on my new 2026b GMC Canyon and from da one it leaked, they are trying there best to correct the problem, but on luck yet.

Everyone I deal with is friendly, helpful and courteous.

Staff and service was exceptional. Thank you for your time and effort.

There’s nobody better in the State of Connecticut than Tom and his team at D’Addario Buick GMC. Their expertise, service, and commitment are simply unmatched.

completely satisfied

Outstanding service department

Brought my truck in for an oil change. I expressed that I had a concern with a squealing noise that my truck had started to make after I made my appointment for the oil change. I provided all the information I could bout the noise.I was told a tech would look at after the oil change. Upon completion I was told that " I shouldn't be worried about the noise." I said a truck that is a year old with 14,000 miles on shouldn't squeal every time I accelerate. The person with my paperwork said " Yeah that's just how it is". This is the 3rd car I've purchased here. I certainly don't think a truck that costs roughly $70,000 should squeal when I accelerate. I didn't find the explanation acceptable and had I had more time I certainly would have put up more of fight about it. I will absolutely think twice about using you for service in the future.

Professional and very convenient, been going there on and off for 40 years.

They service my vehicle at a good timely fashion.

No issues, dealership has always been very good to do business with, and their service department has also been very good. I have recommended this dealership .

Excellent service, thank you

Excellent! Service was amazing, our salesman Tyrell was great!

D'Addario is a great place to buy and service your car. Michelle C. Is always helpful and courteous.

The wait was long several hours for 1st appointment.

Supposed to have OW4 0 and they put out 20 that's not good

Customer service was excellent from the minute I first walked in the door until I drove my new Buick Envision off the lot. I couldn’t be more pleased. Thanks to all who made this so easy.

Everything delivered as advertised. Thanks

Your dealership installed a Tonneau cover and I was never told it would leak I was told by your dealership after having my truck for 2 days there is nothing else they can do I should have been told this BEFORE I purchased it Very disappointed!!

Professional always making sure all your request are being taken care of I would recommend to friends and family

They have been servicing our car since we bought it new in December 2019. They always do an excellent job and keep us updated as the work is done.

Staff was great service is great time was good very clean friendly environment top shelf work

Michelle is the best!! She is friendly (always remembers my name and greets me with a big smile), professional and informative. She makes the process of car repairs a pleasant experience. The cashier is also very nice, friendly and professional.
