I purchased a used vehicle from Mike Juneau's Brookfield
I purchased a used vehicle from Mike Juneau's Brookfield Buick GMC last year, and a few months later discovered a mechanical issue that needed attention. The problem was something that really should have been noted or recognized during their pre-sale inspection and preparation. I reached out to the dealership, explained the situation, and provided the relevant details. The team was incredibly responsive, professional, and apologetic from the very first interaction. They reviewed everything quickly, took full responsibility, and agreed to cover the entire cost of the repair at the shop of my choice, no questions asked and no hassle. In today's world, it's refreshing to see a dealership step up like this, especially for a used car. Their accountability and willingness to make things right completely restored my confidence in them. If you're in the market for a Buick, GMC, or just want a dealership that treats customers fairly and with integrity, I highly recommend Mike Juneau's Brookfield Buick GMC. Fantastic experience, thank you to the entire team!

I just wanted to say Tim Hoffman in service exceeded my expectations. I bought a 2016 CT6 from a dealership in Crystal Lake. I put 300 miles on the car and noticed something was not right with Transmission good thing I had the extended warranty. Tim coordinated everything it was a big job and he coordinated everything with warranty company and kept me updated on status. Thanks Tim one of the best dealership experiences I have had with a dealer. Al B

The only thing is I wish when I got my 2024 Buck Envista they would have told me to wait until 2025 or 2026 to get that car because they added so much more to the model that I have and that really sucks.
