Went in knowing the car I wanted, Buick Envista 2025.
Went in knowing the car I wanted, Buick Envista 2025. Met up with my salesman, Joelle. He did such a great job. He was passionate about auto sales and you can tell. There was zero pressure to buy. Didn’t haggle with me. The finance guy Tavian was amazing as well. Didn’t pressure me to buy anything extra and worked to stay in my budget. I am glad to be a part of the Kendrick family and look forward to buying my next car from them.

Capital Buick Service Department
Capital Buick Service Department has truly outdone themselves with strong regards to a remarkable Customer Experience, superseding mediocre Customer Service - because, yes, there?s a distinct Difference!!! They?ve been servicing my vehicle for the past six and a half years and I?ve Never, nor Will Ever consider patronizing any other dealership or auto body shop. The dedicated assessment, consideration and astute attention Team Leader Doug Aldridge provided, gave me peace of mind in preparation for my extensive ?road-trippin? ? journey ahead. I highly recommend entrusting this establishment with all of your car maintenance, detailing and repair needs. Thank you Doug and Allen for being Professional, Accommodating and Reliable - you both are Greatly Appreciated!!

The customer service was great.
The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.
