WOW, this was absolutely the best experience ever.
WOW, this was absolutely the best experience ever. I picked a car out online. Got pre-qualified. Got a call in 5 minutes, got completely approved in minutes. And a rate that surprised me bigtime. Thet scheduled me an appointment for yest drive. It was waiting for me. Gavin, Jennifer, and Nicole were awesome. Made me feel special. I saw other customers also being treated amazing. This place has it figured out. I will only ever buy from Carmax. And the bonus is that the SUV is mint and looks new. A million thanks to all that made it happen.
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

A very pleasant and encouraging engagement.
A very pleasant and encouraging engagement. The experience could not have been smoother. I’ll tell everyone about them.
Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Kristy is the absolute BEST to work with!
Kristy is the absolute BEST to work with! From my first van, then to my carnival and everything in between I have never felt rushed or pressured to buy! The whole Pilsons team makes you feel welcomed the moment you walk in the door! She posted the palisade and I knew it was the one. I messaged her on a Friday evening and she had me test driving and giving me all the details Saturday morning! Fast forward a couple days(after driving to make sure it was a good fit ;))and I was signing papers! I would recommend Kristy to anyone looking! She will go above and beyond for you!

We recently purchased a new GMC 2500HD from Thompson
We recently purchased a new GMC 2500HD from Thompson Buick GMC. This was an out of state purchase for us, we live in Mississippi 500 miles away and Jace made the entire experience outstanding. He was incredibly professional, kind, and easy to work with from start to finish. Jace took the time to answer all of the questions we had before we made the trip there, (out of state sales taxes, financing, etc) When we arrived, they had everything ready for us and we had everything we needed. Chris in Financing was outstanding as well. He made everything smooth and easy. He took the time to explain all the facts and figures in a way to make it very easy to understand. I can honestly say this was the best buying experience we’ve ever had. Everyone we interacted with was very helpful and accommodating.
