Had the pleasure of having Nick Majeske provide us with an unbelievable experience of buying a new car. From start to finish and even after we purchased our car, his support and genuine desire to make sure we were satisfied did not go unnoticed. What really stood out to us was throughout the process, Nick was transparent and honest, which I greatly appreciated. He kept us informed every step of the way, and there were no surprises or hidden fees. His professionalism and integrity are truly commendable. We could not be happier with our purchase and overall experience throughout it all, and we would like to think this was in all thanks to Nick.

Just want to comment on the outstanding effort & style of salesman Mike Pehl. Spends whatever time & effort needed to make things happen. This is a late review as I leased a 2015 LTZ Equinox. Just wanted to him an atta boy. Thanks again Mike.

Thanks for your help! This dealership offered a great deal that I couldn't pass up on. Glad to have worked with them to make this happen. I am particularly appreciative of the no-hassle and no-pressure environment that the salesperson, Cody, did a great job fostering. Looking forward to working with them in the future!

I will return. Best service department in Waukesha. And I have been to several of them.

Mr Biddle is pleased with the work and professional service Solomon has demonstrated in fixing my Yukon and he helped in getting all parties involved. Thank you Solomon and crew !!!

Overall pleasant experience. I had some issues arise in the purchasing process, but they were all addressed timely and satisfactorily. Nice people to deal with.

We have used this Cadillac dealership to service our Cadillacs for years. This time, we dropped the vehicle off to be serviced the next day . . . however, later that afternoon the phone rang and our car was ready to be picked up - a day early! What impresses me about this dealership is . . . the friendliness of their staff, the cleanliness of their facilities the quality of their repairs - all just top notch!

After having an oil and filter change, we noticed a swishing sound. My husband pulled the air cleaner and discovered that some 'tabs' were not place properly. He fixed the problem and the swishing sound diminished. Not a big deal, but it would be nice if it wasn't there.

Overall great experience in and out experience was great. They got me in and out paperwork didn?t take more than an hour overall great experience.

No pressure car buying experience with Chad Braeger. He answered all our questions that we had. When I went back a week later to pick up the vehicle from having accessories installed, Chad met me at the door and answered any follow up questions I had with the vehicle.
