We are here from Texas and in need of an oil change. We were able to get an appointment and completed in great time. The hospitality of the staff was remarkable and the other customers were nice as well. Great environment.
Very nice truck.
Very nice truck. Only thing missing is massage seats and better fuel mileage with Premium fuel. Otherwise, I love it as it is still makes heads turn.

Jeff Wasson and Charlotte were easy to work with. The dealership is very nice indeed.
A great vehicle
We got a very nice deal on this one owner doctors wife's automobile. The QX 80 is a fine SUV to travel in and around town as well. It's very safe, has plenty of power and has all the bells and whistles that limited edition should have. The fuel mileage is excellent for such a large vehicle with this much power. And it will pull a camper or trailer with ease. All weather driving is not a problem at all. We love it.

Bill Money and the entire service team are incredible.
Bill Money and the entire service team are incredible. Service departments at other dealerships have seemed like a cash grab, but at O’Steen they actually take care of you.
Looked for an suv that could trailer a 7500 pd cam
Everything is great except the rear view camera very poor not hd also could use a built in brake controller for our camper also i dont think it can detect a stopped car

Wonderful Experience!
Wonderful Experience!! They don't add an additional 1-2% percentage like the big dealerships do onto the interest rate, utilizing local credit unions for financing. Lower dealership fee than anyone around and offered more for my trade in than any other dealership from Longmont to Colorado Springs would give me. The buying experience didn't take hours of haggling, in and out satisfied we were getting a good deal. I love my new/used vehicle!

I recently purchased a used 2020 Nissan Altima, and I couldn't be happier with my decision. From start to finish, the buying process was smooth and stress-free. The dealership was incredibly accommodating, and I never encountered any issues throughout the process. A special shout-out to Michael, who went above and beyond to make sure I got the car that was right for me. His assistance was invaluable, and I'm so thankful for all of his help! He was wonderful !
