Just wanted to say thanks again to Kevin Olmstead for all
Just wanted to say thanks again to Kevin Olmstead for all of his help and effort in getting me into my new vehicle. Kevin continuously kept in contact with me with any questions I had or information I was seeking out and also handling the communication well after business hours. A fabulous and dedicated specialist and my first experience with him. I'm also a Feldman CDJR customer as long as Kevin is there. Terrific job again Kevin. Thanks Feldman CDJR.

One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

George did a great job.
George did a great job. Needed a mirror replaced on my GMC 2500HD after a wildlife collision. George was on top of my claim the entire time and expedited the service.

Purchased a used BMW they acquired in a trade in
This was a great transaction. I live about 250 miles away and we did this deal over the phone. The car was advertised very accurately. It was detailed very well and they even filled up the gas tank. Thank you for the friendly service and making this easy.
