I found a vehicle for my daughter that fit all the
I found a vehicle for my daughter that fit all the parameters that we were looking for at Copeland Chevrolet, which I have never visited or dealt with previously and it turned out to be one of the best buying experiences I?ve ever had in the past 35 years of buying vehicles. I worked on the floor directly with Kevin, who worked with me from start to finish and during this time I met Mr. Buchanan, who answered a ton of my questions about this used vehicle since I?ve never even purchased this brand before, Mr.Matta with car warranty questions and had an opportunity to speak with Mr. Reed, who was also exceptional to deal with, was positive and super informative. It?s people like these that make consumers like myself come back over and over again. Thank you all for making this experience such a great one and I look forward to returning in the near future to get something from my wife.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!
