New and used 2025 Cadillac OPTIQ for sale near Lone Tree, CO

We had a very nice experience purchasing a XT4 from John Elway Cadillac. Our Sales Person, Delmar Fralick was very nice and very knowledgeable. He made us feel very comfortable throughout the process. David Kaizer, the Finance Manager was also very pleasant. Both of them made our purchase very easy and we felt no pressure. We had done a lot of research beforehand and that helped us as well. We have purchased many vehicles over the years and this is the best experience we have encountered. We will definitely be back when we are ready to purchase another vehicle. Thank you Delmar and David! You guys are awesome.

We had a great experience working with this dealership and Leon! From the moment we arrived, he made us feel welcome, informed, and never pressured. He took the time to answer all our questions and assured us they were going to get our deal handled. Leon made the entire process smooth, honest, and even enjoyable. If you're looking for a no-hassle, trustworthy experience at a family-owned dealership, ask for Leon. Highly recommend!

Delmar was excellent to work with. He was responsive and clearly communicated throughout our car buying experience. I would recommend him to anyone looking to buy a new car.

I had a blowout tire. Thank You for your service Jason, staff for getting me back out the road.

This dealership was amazing and I highly recommend. When purchasing my new truck, they worked with me to find a price that worked for the both of us. Then when I was an idiot and did not see hail damage due to frost, they further helped by paying for half of the hail damage repair. 5 stars is too low. Eric was awesome and all the managers were amazing. Can’t speak highly enough.

Amazing! Always such great service. The staff is wonderful, so friendly and kind. I went for an oil change and they were so quick and efficient.

I inquired about a Camaro Convertible that had just arrived, Pablo replied and actually sug the car our if the snow and did a complete video walk around. Since I live 400 miles.away and this was exactly the car my wife wanted I was excited to have Pablo helping me. I asked him to look into the price and I had one more to call on. I called back the next morning got the price, made an offer. Unfortunately we where to far apart and the other car sold. My bad luck.

Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!

A huge thank you to our salesman Delmar Fralick! He provided us with seamless car buying experience to help us purchase the CT5 Sport have been eyeing for a while. Communication, the test drive and paperwork all were very smooth. We have bought from Delmar 3 other times at a different dealership and cannot recommend him enough.

I didn't buy the most expensive car on the lot, but you would never know it by the way Austin Roper gave me executive treatment! From the moment I walked in the door I was treated like the most important customer the dealership has. I was given a GREAT deal and FANTASTIC service by everybody at the dealership.

My salesman was Michael Meis at John Elway Cadillac, they treated me well. I purchased a used Tesla, they were the ONLY dealer that knew how to apply the IRS rebate up front. No hidden fees or scammy stuff. Michael Meis was great in sales as was Jonathan (manager) and the rest of the team, wonderful dealership experience which is rare these days.
