Great Place to buy a car
I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.

HIGHLY recommend John Elway Cadillac!
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.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Great experience leasing a car
We met Scott Mendelsohn at Stevinson Lexus about 6 years ago and he is the most honest and ethical car sales manager we have ever dealt with and trust him implicitly, so we followed him to Kuni Lexus. The staff we worked with (Scott, Sean, Raymond, and Marty) were all exceptional and extremely patient. Was an incredible experience!

Thoroughly enjoyed buying a car from AutoNation Subaru
Thoroughly enjoyed buying a car from AutoNation Subaru Arapahoe! I got the best price in the market and the best customer service! Jeff Himes was a pleasure to speak with by phone and text before I drove 60 miles to purchase the car. He had everything ready when I arrived and I was able to complete my purchase without any fuss. The hardest decision was what charity to choose for the donation the dealership and Subaru would make related to my new car purchase. I loved that the choices included national and local organizations. Christian Stoley expertly helped me with the financing. He treated me with respect, was transparent about the options, costs, and I never felt like he was selling me something I didn?t need (which I?ve had from other dealers). Bernice was a true pleasure to sit with in my new car and she showed me all the features I needed to learn. Overall, a delightful experience! No overselling. Top notch customer focused service! I only wish I lived closer to bring the team bagels when I have my car serviced.
