I went into Corwin looking for a specific vehicle.
I went into Corwin looking for a specific vehicle. Bailey Reed approached me and I told him I was interested in a truck on the lot. He went the extra mile for us to get what we wanted. He made it easy for us, I appreciate him a lot, he did a good job for my wife and I. This is the second time we’ve bought vehicles at Corwin, it’s our go to place for an honest deal.
Truck is a Solid vehicle overall.
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

Fantastic Experience!
Had a pleasure doing business with Russell Westbrook CDJR for my new 2021 Dodge Challenger! Zaman, Moses, and Jay worked with me tirelessly to make sure I was happy with the car and our deal for it. This is the second vehicle I've bought from them and I'll definitely be back for a third in the future. Highly recommended!
Love it.
I love the new features this truck offers. I would highly recommend this truck if your looking for a Diesel. I provides all the features and benefits you would want.

We really appreciated how dedicated the staff at Huntley Ford were. We spoke on the phone and visited to check out a few vehicles with Daniel. He was very patient and wonderful to work with. Although we didn't purchase a car during our visit, we would recommend that anyone visits the dealer for a great experience.

This dealership doesn’t negotiate price.
This dealership doesn’t negotiate price. I randomly walked in one day and Michel helped me out, he sent me different car options over a few days and ultimately helped me purchase a great car. It was a quick and easy process which I appreciated and also a no pressure environment which was nice.
