Larry Cagle was great. We bought a flat bed F-250 and there were some issues with the truck and Larry got them all sorted out. He was awesome to deal with and made this a pleasure! Would highly recommend you go see Larry in Bartlesville!

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!

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 contacted Ferguson Subaru/Superstore after seeing a vehicle on line. The internet sales person was friendly, stayed in contact with me and an in store sales associate was assigned. Juan, the sale associate, was friendly, knowledgeable and helpful in my decision to purchase the vehicle. I would recommend this company. There were no unexpected issues, no hidden fees, no requirement to finance to get the advertised price.
