Excellent Service!
Excellent Service!!!! I Can honestly say Luis was amazing!! I was in and out. He explained everything I needed to know about my car, the next steps to take when to bring my car back for service!! Went above and beyond thank you for your hard work!!
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.

That time again!
Loved working with Brandon Hamilton and his GM. Hope to work with you in the future!
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.”

Very Happy
Very pleased! We test drove several cars before making an offer on a 2005 Chevy Malibu. Matt was willing to deal and we got the car within our budget. Great experience! Well run, family owned business.
Car is a pleasure to drive.
My vehicle is an excellent car to drive. The CT6 is a great handling, smooth, comfortable driving vehicle. This is my third Cadillac that I am driving and plan on continuing to drive one.

I sent a msg about an Equinox they have listed.
I sent a msg about an Equinox they have listed. Someone from the dealership did message me back within a half hour. I had asked two questions which did not get answered when they replied. I was asked to call a specific person and then given the name & number to call.

My experience was very good.
My experience was very good. Gavin was a good salesperson. However, I would NEVER EVER recommend a salesperson to tell ANY customer to put down $14,000 which was incredibly obscene for a down payment on a 3 year lease. You should NEVER be that hungry for a commission. My favorite salesperson that I knew for 35 years at West Herr East Aurora would never recommend that to me. That is the trust you build with your salesperson-customer relationship. If I had to do this all over again--I definitely would NOT. It was too late to back out of this deal. Basil is known for great deals, and this was definitely NOT a great deal no matter how you spin it. I was under much pressure myself to get a new car due to previous lease expiring, tariffs coming into the mix soon and my mom having cancer with only a few months to live. But, this scenario will never happen again, I will make sure of that.
