Fantastic place to buy and service your cars.
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.

GM RECALLS ABOUT TO LOOSE CUSTOMERS
I made appt. For recall parts however after making that appointment, and leaving car there for 2 days, was told no parts for repair available. They are available in Florida so it appears I should have had it done there. Bought two cars from this dealer and have always been pleased until now.
