Things started online with just a couple of texts back and forth. Then a couple of phone calls given some positive information. I received some online quotes which we discussed back and forth. I had known what I wanted and Jesse had the vehicle. I sent a few pictures of my trade made a deal and here I am driving a new GMC AT4. I was given a very good price for my trade and Jesse handled everything to make my experience one of the easiest car buying experiences ever. I have already talked with a number of friends to look up Jesse. I thank him for all his help.
I had a great experience at Billion GMC. Adam Limmer did a great job taking care of everything I needed. He listened to everything I wanted in a new vehicle and delivered! Great service and communication all of the way through the sale. Thanks Adam!
I had a GREAT experience in getting my new Buick Envision from Sioux Falls Billion! Nick was so nice & patient with me, no hard sell or pressure! He let the car sell itself. Jeff was also great giving me a thorough tutorial in operations & the 30" dash screen & all the great things on it! I'm loving my new Buick Envision!
Mark has been very helpful and responsive. He has made this transaction very smooth. Will definitely come back for more upgrade on my yukon
We were traveling through town on a road trip and they were able to fit us in same day. Travis was an amazing service advisor and took care of all of our concerns. Brady is the best service technician I’ve had in a really long time. They both listened to the ongoing problems we were having with our 2024 GMC Sierra and repaired what we need to get us back on the road. Thank you to everyone who contributed to making our trip a success!!!!
