CarMax did a good job for me!
I was shopping for a used Chrysler Town & Country Van in excellent condition that had a 6-way power seat on the front passenger side and was white on the exterior. This particular model was very hard to find and CarMax only had about 4 of these nationwide out of about 340 Town & Country vans that they had in stock. I found one on-line that was in Texas that I liked. I contacted Brian Bricken and he started the process of having this particular van transferred to Tulsa. He called and let me know when it was here and ready to test drive. Brian was very easy to work with during the entire process. I test drove the van and liked it. Then I went through the actual buying process at CarMax which was quick and painless. Once I bought the van I took it to Christian Brothers Automotive on 81st street and for $99 plus tax they did a very thorough inspection and only found a few minor things that they recommended to be fixed. I then made an appointment with the CarMax Service Department and Bob helped me through that process. He gave my an appointment to bring the van and have their tech go through my short list of things that needed fixing. They replaced all the windshield wiper blades. They purchased and installed a rechargeable flashlight that was supposed to be in the van. They they ordered a plastic threshold to replace on that was slightly cracked. They also replace a piece of weatherstripping that had a minor tear in the black rubber. I am very pleased with my entire CarMax experience. Now I understand why there are so very many vehicles running around town with "CarMax" emblems on the rear of the vehicle. The next time I need to purchase a vehicle I plan to go on-line and see what CarMax has to offer.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Great Service Dept. experience
I had to use this dealership for the first time for some warranty work on my Explorer. The Service Dept. was outstanding. Top notch service and everyone from the phone person that scheduled my appointment, to the lady courtesy driver, were super friendly and very professional. The experience was a very positive one and they will be my new Ford Delarship here in Tulsa, so much better than the one I was using. Thank you Riverside Ford for being an outstanding Service Dept.

Shopping for a new or used car to replace
I have never met a sales crew that worked so hard to meet our needs. We had challenges in our credit & yet they were able to get us financed with down payment & terms acceptable to us. Our sales person Brayden was the best. He made us feel comfortable & he was very professional. I will definitely be a repeat customer & will request Brayden’s help when we do. The dealership was clean, had great snacks & very comfortable lounge area. A wonderful experience. Thank you Patriot & Thank you Brayden

These guys will bend over backwards to help find the vehicle that you are looking for. My entire experience at Patriot was simply great. I highly recommend visiting Patriot before you look anywhere else! They have a pair of awesome Derricks that will guide you through the process, but their crown jewel is Devon in financing. Go see him! These guys went above and beyond to help me to not only find but also afford my beautiful ride! I am so very happy that I will return to Patriot for my future vehicle needs and you should too! 🥰

Dealing with Patriot Chrysler was a great experience.
Dealing with Patriot Chrysler was a great experience. I drove 876 miles from northern Ohio to make the deal. Driving 13 hours hoping that the vehicle is how it was presented. After making a nice offer on my trade, we made the deal. I was heading back to Ohio with a smile my face. Great experience. Thank you!

I had a great out of state car buying experience at Suburban Chevrolet in Claremore, OK. Allen Marrs made me feel very comfortable from the first phone call. He offered to hold the car until I was able to get there. He gave an accurate description and everything was as promised. Everyone is very friendly and helpful. The car is so nice I may never have to buy another, but if I do I’ll shop Suburban Chevrolet!
