Was charged for more than was done to my car with the last visit. I paid it and then got home and recognized the mistake. I called and spoke with Ben and the problem was corrected and he refunded me a check for the difference. Although I recommend them for correcting the problem, it shouldn't have happened in the first place. What if I hadn't checked the invoice?


Great service

Tonya Hunt my car sales lady was very helpful and through in explaining the car and getting me the best deal possible for this vehicle. I would recommend this dealership to anyone. Positive attitudes and its all about the customers.


"Great service"

My experience at Thornhill Super Store was good. I had my car serviced and the tires rotated. They did what I asked them to do. The waiting area was pleasant.


Great service beautiful dealership

Very comfortable for a women to take her vehicle in around a group of men. Very clean and nice. Always friendly and helpful. Willing to go the extra mile and help you.



Had a leak in the front driver side around the gas pedal. Took in and found a drain hose that was unhooked. Fixed the problem. Very helpful to set up appointment ASAP before carpet was destroyed also. Only issue is I felt this was covered under 3 year warranty and it was not. Labor charge was only.


Excellent in every way!

The service was just like I expected it to be - very good!

I took my car in for routine maintenance and for the recall to be repaired. They both were completed very well. I have several issues with several things that needed to be repaired and they were to order the parts, but I haven't heard from them yet. Waiting a reply at this time and am hopeful the repairs will be made without incident.
