I have worked with this dealership for nearly 20 years,
I have worked with this dealership for nearly 20 years, and many cars. The service / maintenance experience is excellent. The sales experience is excellent. And... the cars are excellent.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Excellent experience.
Excellent experience. Professional, patient, and answered all my questions. All the employes were pleasant and greeted me with a smile. I would recommend Jerseyville Ford to anyone looking to purchase a new or used vehicle.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Best car-buying experience I have ever had in over 50
Best car-buying experience I have ever had in over 50 years of buying automobiles. It was simple, straightforward, honest, no-frills (read no added costs), and the large selection meant that I was able to get exactly what I wanted. Online shopping and negotiating was very easy with no surprises when I reached the dealer to make the purchase.

I had an amazing experience at Jim Butler Chevy thanks to Bryan Lagunas, our salesman. From the moment we walked in, he was friendly, knowledgeable, and truly listened to what we needed. He made the whole process smooth, stress-free, and even enjoyable—which isn’t something you usually hear about buying a car! Bryan went above and beyond to make sure we got the right vehicle at a great price. If you’re headed to Jim Butler Chevy, ask for Bryan—you won’t be disappointed!
