An Outstanding Car Buying Experience at South Oak Dodge
An Outstanding Car Buying Experience at South Oak Dodge Chrysler Jeep Ram of Matteson, IL Our recent car buying experience at South Oak of Matteson, IL was nothing short of incredible, thanks to the exceptional help and expertise of Ryan Ganser, the Finance Manager, and Aaron Mathews, our Sales Professional. From the moment we walked in, Ryan and Aaron created a warm and welcoming environment. Their knowledge and informative approach made us feel confident and well-guided throughout the entire process. Ryan's financial expertise ensured everything was seamless, while Aaron's professionalism and personable manner made us feel valued as customers. We left with not just a vehicle we love, but also the joy of knowing we made the right choice with South Oak. We would highly recommend Aaron Mathews and Ryan Ganser to anyone in the market for purchasing a vehicle—they truly set the standard for customer service and excellence.
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.

This dealer had the used car I was looking for.
This dealer had the used car I was looking for. The car had the right mileage and a clean fax. The dealership was 1 hour 20 minutes away from me heavy traffic all the way. I figured I would call and ask about the car anyway but I wasn’t planning to drive there. I talked to Phil, a sales rep, and what a gentleman he was. He told me the car was a trade-in and was in fantastic condition. Well, he talked me into driving down there. I arrived about 10 in the morning and left with my new used car by 1:30 that afternoon. I walked Phil through my 128 point inspection, 2 test drives and I ending up looking under the car for any problems. I could not find anything wrong. The car was in great condition just as Phil had described. Phil was a perfect gentleman through the whole process. Every dealership employee I encountered could not do enough for me. Great experience - great car! 6 star experience!
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Todd was very helpful and made sure my car was pulled inside when leaving as it was very slippery outside
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.

Good for challenging credit
Relatively painless process when you don't have a great credit score to work with. They can finance where major dealerships cannot (will not). They finance in house
