Great Service- Kenmanuel is best.
Great Service- Kenmanuel is best. This is the 2nd time ive worked with him in the last year & I couldnt be any happier!
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.

Outstanding Experience
Because this is such a wonderful vehicle, I purchased it at the end of the lease. Dan and Russ were incredible in making this a seamless transition. My vehicle was inspected, rims repaired, appropriate services rendered, thoroughly cleaned plus received an excellent offer for new tires. I have been trading for many many years with Dan Ramsdell and his team. This experience is once again reason to make the John Thornton family of dealerships my only source for our family vehicles. Highly recommend this team now, just as I did three years ago. Thank you!!! The lease of my new 2020 Chevy Blazer was flawless. This was the third vehicle that I've leased from Dan Ramsdell. We have worked out the details on this transaction (all three) via email. I took limo from Atlanta airport to John Thornton Chevrolet, they opened at 8am just for me. All documents were ready, I only had to sign them and was our in thirty minutes. This gorgeous Black Blazer AWD 3LT has been detailed, filled up with gas, my all weather floor mats put in place and temporary license applied for tag with requested black license plate frame. Derek Strickland saw to it that everything was orchestrated perfectly and my transaction was seamless and most enjoyable. I will definitely trade with these professionals once again and highly recommend others to visit John Thornton Chevrolet!!

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!!
