Lavish is a fantastic rep to deal with, take my advice and ask for him
My beautiful little Chevy Spark spinned on a snowy country road and smashed into a pile of firewoods. The front of it got completely crashed. When I handed it to Eastside collision centre, I wasn't sure how they will fix it up. After 10 days, when I saw my brand new looking little "baby car" again, I was...

Lovely people from diagnosing the problem to it being fixed including a lovely young lady who checked out our car. We had such a great experience here and trusted them completely. Thank you this is very hard to find.
Danny was fantastic through the whole process from start to finish!!
By far the best service I’ve ever received from a dealership service department. I called in because my car broke down and I live over an hour away, so I was extremely stressed and worried I’d be stranded in Markham — especially since I had just started a new job. Even though it was only about 2...

My beautiful little Chevy Spark spinned on a snowy country road and smashed into a pile of firewoods. The front of it got completely crashed. When I handed it to Eastside collision centre, I wasn't sure how they will fix it up. After 10 days, when I saw my brand new looking little "baby car" again, I was like: wow, they did such a great job! I can't help write an email to the manager Danny: "You should be proud of yourself! Your job is like mending and fulfilling people's lives, at least for me, my little spark is a big part of my life." Of course it's a big bill, but considering what happened to my car, and the hyperinflation environment right now, it's pretty reasonable! Over the course, Danny communicated with me in great details: lots of pictures during reparation, detailed price breakdown, suggestions about parts used (if the aftermarket parts work or not). I felt released knowing the progress of the repairs. They predicted in 10 years that AI will replace 90% of human work. We are forced to learn more and more AIs are going to take over the world. But for sure I won't embrace that kind of future. And I believe the job that done by Danny is irreplaceable. He gave the human touch to my little car, and the human interaction is what the value lies within. This kind of quality customer service is what I wanted and treasured. Highly recommend to anyone who appreciates great customer service like I do.

By far the best service I’ve ever received from a dealership service department. I called in because my car broke down and I live over an hour away, so I was extremely stressed and worried I’d be stranded in Markham — especially since I had just started a new job. Even though it was only about 20 minutes before closing, Mega took the time to help me, arranged everything quickly, and made sure I had a rental so I could get home safely. Her professionalism, empathy, and willingness to help truly went above and beyond. I can’t thank the team at Eastside Chevrolet Buick GMC Corvette enough for turning a very stressful situation into a positive experience. Highly recommend.

Their salesperson Costa went above and beyond to make my purchase as easy as possible showing great attitude and agility, providing clear information and helping throughout the whole process 24/7. The whole process went smoothly and quickly, service was at the very high quality level from both - technical and administrative perspective. Highly recommend. Thank you Costa and others.
