We needed service on our Sierra and found Thompson GMC in Springfield. Every step of this visit was great. From booking the appointment, to driving in to drop off the truck. The shop is very clean and things were run well. We were updated along the way and our work was done as promised... And my car was washed! Our service advisor, Austin, was great. We will be back

Ken in the service department was the one who kept everything from stalling. He stayed engaged, handled questions cleanly, and made sure the customer’s service plan stayed on track.

Chance Sigman has worked with myself and my mother in the trade in and purchase of two cars since the first of the year, 2026. Chance was exceptional in finding each of us exactly what we both wanted. Carol in finance worked very hard as well in meeting both of our needs. My mother is very happy with her purchase of a brand new Cadillac and I am extremely happy with my purchase of a used vehicle. We were both treated like family every time we walked in the door at the dealership. I will be back to Thompsons in the ... Read More

Easiest and best vehicle buying experience I’ve ever had. From start to finish, every single person I’ve been in contact with at the dealership has showed exceptional customer service. Our salesman, Bobby Duncan was phenomenal to work with. We live 3.5 hours away and the whole deal minus signing was through phone/text. Bobby made it super simple and fast. Adam in finance was great, he got us in and out and made the process easy. Not only did the customer service sell us, Thompson’s prices beat many other dealers. I know where we will be coming for ...

Not a great experience from a dealership that is supposed to have a high reputation. We inquired about a vehicle that we had saved on Cars.com. It was listed in December. The first day we inquired we asked questions about the vehicle and had a plan to come see it approximately a week later. Communications were sporadic and some of our questions never got answered. We were possibly going to trade in our vehicle that we had previous offers on. I explained that we would need to get the same or close to same offers for ours as the ... Read More
