The service manager was outstanding.
The service manager was outstanding. He was involved in every aspect of my car repair. My issue was very difficult to diagnose. I observed him interacting positively with employees. I saw him doing manual labor, which you usually do not see. I was greeted positively from the moment I arrived. This is in contrast to the negative experience at AutoNation Chevrolet Pembroke Pines down the street from me. I know a positive business from the moment I walk in. I observe all employees including the amount of time spent with customers or just in the customer area. Happy employees are going to give customers a better experience.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

We were on a road trip from Minnesota to Florida and a loud banging noise started in the front of our car when we were in southern Iowa. Since no error messages were on the dash we kept going until we saw Poage south of Hannibal. We stopped and the mechanics found some bolts had come loose on a dust cover and it was banging against the drive shaft. After putting it back in place, we were on the road within an hour. The care and efficiency were top rated. They said that it was so minor that they weren't even charging us for it. Wow!

I purchased a 2017 Mitsubishi Outlander from Butler's
I purchased a 2017 Mitsubishi Outlander from Butler's back in 2018 for my growing family and it was a great car!! I just recently was able to trade in and upgrade for a beautiful 2021 GMC Acadia and Noah went above and beyond to help me find the right car. He was so patient, let me drive all the cars I had seen online (even stayed late to do so) just to be sure I was making the right choice, answered all my questions in stride, and also helped me weigh my pros and cons for each choice I had. Noah made the process effortless and I will HIGHLY recommend Noah, Todd, Tyler and the rest of team at Butler's to anyone needing to trade or find the right fit. Great people, excellent customer service and I'll be calling them before anyone else when I'm ready to trade again.
