Just had my 60,000 mi.
Just had my 60,000 mi. Service and all went well! They also repaired a rain leak I found after the last storm. I?ve bought several autos from Jim Ellis and always have been pleased with sales and service . Ted and Harley in the Buick service dept .are the best!! I would recommend this dealer.

Scott S.
Scott S. was a great help to me with the sales team. Met Scott for a test drive, and he was very knowledgeable and helpful without being pushy. The service department had to work on the truck I was interested in before it was ready to be sold, and he kept me updated and informed throughout the process. Although I ultimately bought a different vehicle, it certainly had nothing to do with Scott. Would happily reach out to him in the future or recommend him to anyone else in the market.

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.

I always receive excellent service from Colonial.
I always receive excellent service from Colonial. Last time they stressed how important fuel injector cleaner is for my vehicle, however this time they didn't mention the cleaner and when I brought it up they said they would take care of that next time. How important is it really? Just left me wondering and thought I would mention it.

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!!
