Suntrup Buick GMC review
We just replaced our 2022 Buick with a 2024 Buick Encore GX. Vivek Abraham is very helpful and does a wonderful job as a sales person. Crystal Mc Elroy is a wonderful sales manager and she is the reason we keep going back for more cars. The entire staff is helpful and we had an easy buy. We do our service at Suntrup Buick GMC too They have been very fair on tires and overall maintenance for our cars over the last 15 years.

Nick Pashos did an amazing job taking the time to make sure I was happy with my purchase. Michael Minner was great in finance with explaining all the details and working with me financially.
2026 GMC Sierra 3500 review
Overall pretty good, however it is undocumented if you turn off or adjust some of the safety setting it will cause light on dash to come on and make you think issue with system (ex collision if you change from default of alert and brake to alert only). I think this is an issue and should not light dash light to indicate an issue with the system because of alert settings.
