My experience with Patrick Old Sales Consultant and John Gosa Finance Manger Was very exceptional, and extremely helpful through the entire process of purchasing our car! We very much appreciated their help with the financial assistance offered to trade in our old car for the new one and they went above and beyond to help make this process so much easier for us! We will absolutely do business again in the future! --Michael Noyes and Steven Gardner thank you so much!

All the staff I spoke with were friendly and courteous. Tito was a great salesman and very informative about all the features and details that came with the vehicle I was interested in. Communication was also strong. All of these factors made the buying experience much more enjoyable!

Outstanding personal attention and helpful information even after the car leaves the lot. I have purchased 2 cars and will be back in the future for any other family member vehicle need.

If you want a no pressure car buying experience with folks who truly care and not out to simply “close the deal”! See Samuel Michel @Thompson Buick GMC of Springfield. I have purchased many cars in my time and this was one of my best experiences. They did not try to sell me anything I did not want. 10/10 recommend!

I just changed dealerships for my 2019 Terrain service. It was purchased at my former location.. The Service Manager was very helpful.

Deon Greenlee was great! This is our second experience with Thompson Sales and they once again did not disappoint. Their level of service and professionalism is above the 5 star rating and the bonus is that we love our new truck!

Mike Peters was the most helpful, informative, knowledgeable, and pressure less salesman. Thank you for all of your insight! You made the process so streamlined and our family loves our new ride. We like Mike! :)
