Great and easy experience.
Great and easy experience. Sales staff was easy to work with. Car is fantastic. Price was reasonable. I would recommend the dealership to a friend.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

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.

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.

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.
