We purchased a Denali truck from Derek Couffer at Thompson Sales Company. His knowledge of the vehicle left us with hardly any further questions. The dealership is very professional and welcoming. Purchasing a vehicle here was a great experience!

My experience with Thompson in Springfield exceeded my expectations! The staff as a whole were absolutely remarkable. They were so kind & patient with me, and what a breath of fresh air it was to deal with bright individuals. A few hours prior to buying my new Buick from Thompson, I shopped at Mayse in Aurora & I was given a half-ass attempt from a salesman to sell me a car. The atmosphere of Thompson was the exact opposite. I was relaxed and happy, which are two words I never thought I’d use to describe my car buying experience. A big thank you to Thompson from a future repeating customer! Double the 5 stars, let’s make it 10.

Mark is quite exceptional in his field of expertise. I am very pleased with my new car. I would purchase another vechicle from only him. Mark is knowlegeable, professional and and aiming to please the customer. THANK YOU Mark Cotner

I want to Thank Marcus for all his help & for future understanding of my lack of computer knowledge & his patience in dealing with my many questions some good some probably stupid but nevertheless questions about things I don’t get or Why?🤣. He has stayed in touch since my purchase & offering his expertise & services in helping with learning my new vehicle. This is my first experience with Thompson & I’m sure won’t be my last. I’ve also had an experience with the parts department in ordering my weather mats for the SUV & Walker was very helpful as well. Thank you to both Marcus & Walker Cheri White

Just purchased our second GMC Sierra from Thompson Buick GMC of Springfield, and couldn’t be happier with the way they handled everything, especially Tristan Primanzon. I don’t think we could have gotten a more polite and respectful young salesman than Tristan, so if you’re interested in a new vehicle and great service ask for Tristan!

Staff was very courteous and professional. Car was done before estimated time.

Bought our third vehicle from Thompson Buick GMC of Springfield. Primary salesman was Ricardo Gerard for our 2025 Cadillac CT5-V. Outstanding professional to say the least! Ricardo was the most knowledgeable, attentive and concerned salesperson we’ve had the pleasure to work with during a major purchase. The entire staff at Thompson deserve a “High Five” from sales through financing. Thanks to all for a truly enjoyable experience!

We had a great experience at Thompson's with our purchase of the Cadillac Vestiq! Our salesman, Chris Carico was excellent to work with. He was friendly, helpful, and always responded quickly to any questions we had. Digger and Carole were great to work with as well! Such an amazing staff! I highly recommend visiting with Chris for your next vehicle purchase!

Technician Hughes went above and beyond, staying after hours to personally diagnose my vehicle’s window issue when it acted up post-service. His professionalism, kindness, and dedication truly impressed me. Hughes provided exceptional customer care, turning a frustrating moment into a positive experience. He’s a rare gem and a true asset!

Brent Morris did a wonderful job. The process was quick and went smoothly. I did not feel pressured and he gave me options when I asked for them. Everyone there was equally as nice and helpful. I would definitely purchase another vehicle with Thompson.

Very comfortable atmosphere, helpful above and beyond.

I recently purchased a 2025 GMC Sierra 2500 Denali from Thompson GMC, and I couldn't be more thrilled with the experience. Nathan Saderstorm was my sales consultant, and from start to finish, he exceeded all expectations. Nathan's professionalism and knowledge about the GMC lineup were evident throughout the process. He took the time to understand my needs and preferences, ensuring that I found the perfect vehicle. His transparent communication and no-pressure approach made the buying experience enjoyable and stress-free. The 2025 Sierra 2500 Denali is an exceptional truck, and Nathan made sure I was well-informed about all its features and capabilities. He patiently answered all my questions and provided valuable insights that helped me make an informed decision. I highly recommend Nathan and the team at Thompson GMC to anyone in the market for a new vehicle. Their dedication to customer satisfaction and attention to detail set them apart from other dealerships. Thanks to Nathan, I drove off the lot with confidence, knowing I made the right choice.

Bought a 2020 GMC Sierra from Steve Hurd. We had some issues with a bank on my title and it took some time to work through that. Steve and the finance department worked with me and were patient during the process. Gave me a fair trade in and the price of the Sierra was very good. Strongly recommend.
