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.

I highly recommend buying a vehicle from Unique Auto Group! We will definitely buy from them again!
