Overall good buying experience at dealership.
Francisco was very helpful and show the van we bought even while it was being detailed. Also made the buying process simple by getting the all the financing before the van was done. Overall a good buy experience and follow through with getting one of the door locks fixed after the sale,
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.

Exceptional service.
Exceptional service. Debra, Allen, Vinny, and Amanda do so well in making sure their customers are 100% satisfied. This company will go above and beyond to do whatever it takes to meet the needs of their customers. This is the only dealership I have used since I moved to Lawton and will continue using them from here on out. I have purchased 3 cars from them in 3 years and I dont have a single complaint!

Expectations were set and met on a Saturday with college football on. Two separate seating areas in case you wanted the option to watch something else. There's also a kids' area if you have a little one who needs to be entertained for the time you're there.

A surprisingly pleasant experience
Best experience I've ever had with a dealership service department! Michelle and Jack picked up my car and returned it to me!! Friendly, clean, pleasant and competent. So rare these days. I would recommend them highly, especially over Freehold Buick. Freehold Buick tried to rip me off on several occasions. They lied to me and were disrespectful. I'll never go back to Freehold Buick, but look forward to working with Jim Curley Buick of Keyport in the future. Thanks so much.
