Customer Testimonials

It's a different time buying a vehicle today. First time ever I bought a vehicle online. Seaway Chevrolet Buick GMC was absolutely wonderful to deal with. When I picked up my vehicle it was like dealing with long time friends. Thank you Seaway for making buying a car today such a pleasant experience.





Good service


Bruce was amazing to deal with! Made me and my wifes van shopping experience 1 to remember. I will definately be going back for future vehicle purchases

Made a call about a vehicle and I was informed of a better deal so went to take a look and walked in late in the day and got amazing service. Amazing people to deal with, everyone is very friendly and professional. Highly recommend to everyone.



I have went here once to test drive a car. It clearly had transmissions problems. Or was misfiring/not running on all cylinders... or a issue with picking up speed/ it hesitated alot while giving it gas... the service was friendly... but they wanted alot for this car that didnt even drive smooth... I may check back again one day...I like buicks...and GMC of course... my uncle bought his truck here...and it's great.. but it was only 4 years old... the one I was looking at was 10+ years old ...and was very expensive for the mileage/way ...

Thanks Corey and team


Brought my Audi to do its seasonal tire change, oil change, a brake service and alignment - everything went well. They have a few tech's that are very savvy when it comes to imports, they don't only specialize in Gm's. Brandon was great as usual, no issues whatsoever. Everyone is always pleasant to deal with at this dealership!

Just purchased 2 vehicles in the past couple of months with Seaway. Great dealership and awesome salesman Matt Hope and awesome finance manager Cory Maxam, they treat you very well. I would have given a 5 star however we've been having a bad experience with one salesman Derek, his office is the first cubicle when you walk in dealership and he is just too aggressive for me and my family. He doesn't stop pestering us even though we tell him we are here to see Matt or someone else. He made my daughter feel very uncomfortable every time we went ...




Excellent service every time, great team.



Emergency service was needed while travelling. Service department went above and beyond to get us going again. Many thanks.

Amazing service as always, Seaway GM Cornwall services all my family vehicles, even the non Chevy’s. I trust their word and their experience staff for all our needs.

Took my 2013 2500hd in for a no start issue. Was pleasantly served by Amy in service. Was kept informed of the work needed and the time It would take. As planned my truck was ready and had a new fuel pump and a throttle body installed. The cost was very reasonable. Thanks guys for getting the beast back to work!




Pleasant staff very helpful and very welcoming. The place is so very organized you can see everything you need clearly. And there is always someone there to help.

I love the drive up that Seaway offers for oil changes. I don’t have much time for this type of thing as I have to travel some distance from home to work(between Quebec and Cornwall) They are fast and efficient and a fare price. Would highly recommend them.

Great!! Friendly and fast service!! I have always stuck with seaway gm in Cornwall for all my vehicle maintnance. I would recommend them to anyone!! Thank you


Inspiring and positive experience! I live my life with the philosophy of 'give even if you only have a little with love, care, compassion always!' Corey Wheeler and team at Seaway GMC are all that!! These individuals are honest, hard working and genuine, I am proud to be apart of the seaway GMC family. Staley Family








Amazing customer service, the service advisor was just outstanding, always letting me know the exact issue, if it's important to fix right away or not, he made sure everything was done exactly the way I wanted, even took the time to answer my questions, couldn't ask for better service

Traded in my truck for a newer one. Great staff and very friendly. Derek was the salesman assigned to me and I couldn’t be more grateful with the help.




Thanks for a job well done , everyone was using safe COVID protocols, the service was quick and easy and I was in and out in no time.

I have been lucky to have a Volt trained technician that has looked after my vehicle for the past 7 years. I cannot thank the team enough for keeping my car in running order so it can run well past the 300,000km mark. Best car I have ever owned, thankful for a great dealership.



Derek was very helpful in providing me information on the ordering process for a new car. Had a great encounter with This dealership!

I have to admit that I was prepared to do battle with the service dept over any charges that might have occurred while my car was still under warranty but much to my surprise there were none . Thank you Seaway 😊

Great bunch to deal with. Great service dept.

Bruce is the reason I would buy a car at this place...down to earth...and recently parts staff was very helpful when I was repairing my own brakes.



Great friendly service fast clean and professional.

No problems at all. Tires were put on and balanced.




Bought my wife's first car here. Didn't get pushed around and had great service when buying and or going for car maintenance.



This is the 3rd dealer since i own my truck. This one is a keeper. Excellent service and staff. No stress. Not complicating. Easy to talk to. They take time to answer questions. Great follow up. I will be sticking around.

Simply put. Service and Parts was wile GM expensive totally efficient, accommodating and helpful on a crisis situation

I originally made phone contact about a vehicle I was interested in. My contact Bruce was very receptive in accommodating with my inquiries. I live at least an hour from seaway gm. He personally took pictures of different vehicles and sent them to my phone. As result I now wanted to do business with him as I felt he had a genuine interest in helping me. In the end it resulted in a sale also providing me an attractive buyout on my trade. Bruce is very knowledgeable in what he does. Simply. Some people get it. And Bruce certainly does

We had such a positive experience after our SUV gave us some trouble as we passed through Cornwall. Thank you Brandon for your help in expediting the needed repair and George for your friendly shuttle services. We're very appreciative of you both!



Everyone at Cornwall Seaway Chevrolet Buick GMC deserve a 10 for the service we received last week. Thanks to all.

We were visiting Seaway Motors for a battery service update recall for our son's Bolt and we were impressed with the courtesy, professionalism, and the coffee and donuts supplied by the Service Staff during a visit which took longer than usual. A special shout out to Corey the Service Manager.


Started with an excellent experience with Cornwall Towing--truck was delivered to Seaway GMC--thought it was the radiator--turns out it was a broken clamp--good diagnostic by the technician--truck runs good--thank you


Super great service! Fast and friendly staff. Same day service.

Excellent customer service amazing staff that kept in touch with us throughout the day with any issues they saw.

Thank you for your excellent service.


Great service. Very impressed!!





Very professional and courteous. Especially the service rep Jean. He was very knowledgeable, polite and helpful. The manager, Corey was also very helpful. Bill O’Brien


It took us a couple of weeks to commit to trading and purchasing new, and our sales person (Janice) was very patient and helpful. Even when we had a minor problem with the left blinker, on delivery, she tried to have the problem resolved as quickly as possible.

Technical Assiustant took the time to explain what needed to be done. Because the parts had to come from out of town, the work was done in a timely fashio.

I brought my car in for both a recall and a leaky transmission. My transmission was under warranty so that was a definite bonus. They took care of both PLUS they went above and beyond doing a bunch of other stuff at no extra charge...they didn't have to do that and they did. They certainly are improving their service. Keep up the good work! Colleen

They worked on the car I was giving to my sister all day. The service was really good and they were all very kind. They gave us a loaner car as they worked on the car, so we got all our running around done that day. They called us to update us on the status and asked for permission to do the work that needed to be done for the safty.
