I never bought a vehicle in a more seamless efficient
I never bought a vehicle in a more seamless efficient process as i did with Paulding. The customer service was impeccable and although being out of state i received my vehicle very fast.
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.

Try this SUV before you buy 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.

My Beautiful Chrysler 200
After the horrifying wreck I thought I could never love another car like the last one. Then the fabulous sales staff at Carmax Kennesaw helped me find My beautiful Chrysler 200. She purrs like a kitten and handles like a dream. I couldn't be happier.
There are 20 matching cars close to your year range.
