Shopping for a GMC Yukon
This was my 1st experience with CarMax and I have absolutely nothing but WONDERFUL things to say about the entire process. Everyone that I dealt with, throughout the entire process had amazing attitudes and willing to help in any way possible. I truly felt like everyone enjoyed their jobs and their main goal was to make sure all their customers got into the vehicle that they truly wanted. I can't thank this team enough, for making our Yukon purchase as smooth as it was!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Top notch customer service
The last thing I wanted to do this year was buy a vehicle but HUGE thanks to Amber Genardi and Coon Rapids Chrysler Dodge Jeep Ram for making the experience THE BEST EVER! I have bought vehicles both new & used from various dealerships closer to my area and have never received as wonderful of service as I did from Amber. From the start she had my best interest in mind. She helped find a wonderful used option with every feature I wanted in my next vehicle. The service she provides made me feel no different than if I had walked in there to buy a brand new $60k vehicle! Not only did she sacrifice her time off to work with me around my schedule, she went above and beyond to make sure this vehicle would still be on the lot for me, since I was traveling nearly two hours to purchase a vehicle. To make the whole process even sweeter, Amber gave me an awesome gift basket! She did a wonderful job explaining the features of my new to me vehicle. As well as making it very clear that she will continue to be available to answer questions as I spend more time in my new ride. I will return to this dealership again and look forward to working with Amber for any future vehicle purchases. If you are in the market for a new or new to you set of wheels go see her. You will not be disappointed.
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!

We had a great experience here, our sales professional Scott Gamble did a great job. His knowledge of his vehicles all the way down to what features came with all the trim levels made it much easier to decide. Would definitely buy from them again.
