Adam Keup was FANTASTIC to work with!
Adam Keup was FANTASTIC to work with! I live in Colorado and drove to Omaha with my trade-in and picked up my new Lexus. The whole process was smooth and quick, and Adam was super friendly and trustworthy. Great place to buy a car!
Amazing...and American!
Recently bought a used CT6 w/2.0 Turbo (2018 with 39K miles). Have put only about 500 miles on it so far, but, WOW!!! This car is amazing! This car lives up to it's reputation as a builder of premium American luxury vehicles. My las t Cadillac was a 2000 STS...which was mediocre by comparison. It is soooo beautiful inside. I like that the screen is integrated into the dashboard. It's size takes a bit of getting used to, as my last car was a Mercedes E250. I test drove the 2.0 turbo and the 3.0, and found the 2.0 Turbo to be equally responsive but smoother. Exterior styling is simple clean and exudes luxury. I get so many compliments, heads turns and such. I love the Apple Car Play feature that projects what's on my phone to the in-dash screen. Recently did a road trip and got an AVERAGE of 33.4 MPG on the highway. I am getting 25 MPG+ around town. To me, that's pretty impressive for a car his size. In keeping with Cadillac's reputation, this car drives so smooth and quiet. Last time I drove a car this quiet and smooth as a Lexus LS460. At $30K less than the price of an average EV, it will take a lot of gas to make up the cost difference of those overpriced cars.

A Praise-Worthy American Luxuray Automobile
Having had my 2018 Cadillac CT6, equipped in the optional Premium-Luxury trim level, for nearly 3 years, I can honestly boast of its many attributes. It offers wonderful styling inside & out, the availability of virtually every current "high-tech" option conceivable, and has proven to be consistently reliable – and, while some may describe it as a bit “pricey,” it’s actually a relative bargain, when compared to its European competitors. The CT6 harkens back to the classic Cadillac sedans of years gone by, as its size, comfort, and luxury amenities remind owners and admirer’s alike, of many of those all-American classics. Although it's a pleasure to drive, even when equipped with the new and improved, 3.6L V6, the optional 3.0L Twin Turbo engine is recommended for those drivers who like a “little something extra” when depressing the accelerator pedal. With regard to performance, it is somewhat regrettable that an (optional) V8 is unavailable in the company’s “Flagship model.” This absence, I suspect, is a rather obvious "nod” to the so-called green energy movement that seems to have “infected” the entire auto industry, of late. In summary, if you’re looking for a full-sized American luxury car – look no further. The Cadillac CT6 “fits that bill, to a tee.”

I recently had an exceptional car shopping experience at Auto Boutique. From the moment I walked through the door, the staff was incredibly responsive, addressing all my queries with patience and professionalism. They were genuinely helpful, guiding me through the process without any pressure, ensuring I felt informed about my choices. The politeness of everyone at Auto Boutique was particularly noteworthy; they made me feel valued and respected throughout my visit. I have not yet found a car that perfectly matched my needs but left with a positive impression of what customer service should be. Highly recommended for anyone looking for a smooth and pleasant car buying journey.

This automobile is a vehicle of dreams Power roomy front and back Movies Massaging seats heated and cooling seats. Dual sunroof s. Shades. I feel special just Driving or Riding

Brought my son's Acadia in because one morning it would not shift into reverse and the CEL came on. It seemed to fix itself as the CEL went off. I brought it in anyway to be sure as it did show two codes. Eric and his team thoroughly checked everything possible for a day and a half and determined it was fine but he wanted everything well documented in case it happened again and it was out of warranty. They never were able to get the CEL on while at the shop after driving it for a bit. Great work by Eric and the tech's who worked on it.
