New and used 2026 RAM 1500 trucks for sale near O'Fallon, IL

The technician was amazing gave me updates along the way I will definitely come back because of him

I had been procrastinating going to a car dealership for a while now because the process always takes SO long. I knew I would have to block out a whole day and I just kept putting it off over and over. Finally, I stopped in on a gorgeous Saturday afternoon to look at a used Jeep Renegade and, unfortunately it was already sold. However, I ended up looking at some new Jeep Renegades, fell in love, and the rest is history! First off, from the moment I started looking around, Jerry was awesome! He promptly came out and greeted me and we discussed my needs. After showing me some cars and discussing some options with me, I finally took the Renegade for a test drive. We were chatting so much I almost forgot we were on a test drive! Jerry is great people! Once I decided I was interested, we went over some numbers and Jerry and the whole team kept me exactly in line with what I asked for from monthly payment to interest rate. I could not have been more impressed. Did I mention this entire process only took 3 hours!? 3 hours and I drove away with my beautiful new Jeep. This truly was the perfect car buying experience and I can't say thanks enough y'all!

Went in to buy a new car… Saw a great deal on a used Chevy ended up buying that. Even got to meet the sales manager Mike and had a wonderful time. And the bag of popcorn didn’t hurt either.

Cory at Auffey is so easy to work with. I have leased several cars from him and each experience was delightful. He’s not pushy and shows you the cars you’re interested in. Either all the frills or non of the frills he’ll find the right car for you.

I am repeat customer. Sheryl was my sales person and she was professional and explained everything to me. Great experience and would recommend Sheryl and Fedeico to everyone.

Bill Erwin was so helpful in our purchasing our new SUV. He had all the answers and helpful attitude to help us make our decision. We have used this dealership for years and have purchased several vehicles from them. The service dept has always been great. Thank you Bill for calling and even following up with us that we were all set up etc. This purchase was handled with ease, no stress. We appreciate Bill and this dealership!

Came in for a repair on my vehicle and was also getting a rental the rental department went above and beyond to make sure the vehicle was clean and disinfected and ready for me I was in and out of there in no time at all will definitely be back because of those young gentlemen.

I just purchased my 2nd Jeep in 4 years from Steve Lane at Cassens and both experiences were straightforward, simple, and honestly... fun! Steve is extremely knowledgeable, patient, and courteous and worked with me to get the exact vehicle I wanted both times. Steve was never pushy and truly listened to what I wanted and needed and the finance manager was very straightforward and easy to work with. Both car buying experiences were not the least bit stressful and I left feeling very pleased with the deal I got. I've also always had a great experience with the service department for my routine maintenance - everyone is so friendly and kind and gets my work completed in a timely manner. I've especially been impressed with the service I've received from Mike Keller - he really goes above and beyond to keep me in the loop when my car is being serviced. I cannot recommend Cassens enough!

I got my Dodge Ram 1500 from Federico. Colton was very easy to work with and helped me find something with the features I wanted. Would definitely recommend Federico.

Between my Son & Daughter-In-Law and I we have leased or purchased eleven new Jeep products through Jerry Kasten and Glendale. Great deals, great service after the sale and a solid Finance Department are the reasons we keep coming back to Glendale.

Fast, easy, informative! I felt like I got all the information I needed and great rates!

Ron, and the entire staff are first class! My wife and I flew down from Minneapolis. Ron picked us up at the airport. We took the vehicle for ride & within an hour and a half, we were on our way home. The smoothest transaction I've ever had buying a vehicle.

Jeremy Yingling was a great help getting the best deal possible to replace a stolen van. At an incredibly stressful time he was a liferaft.

Our experience was nothing less than awesome. Alex our salesman went above and beyond anyone we have ever dealt with. He made it pleasurable and seem less!!
