My service tech, Julie, was very professional and
My service tech, Julie, was very professional and courteous. I did not have an appointment for service, but Julie reached out to the service department manager and informed me that they would be able to work me in. My Yukon was running hot and as I suspected, the thermostat was needing replacement. Randy Marion had the part on hand and Julie told me to allow for several hours. The work was done on time and there were no surprise additional costs or fees. The whole experience was why I keep going back to Randy Marion Buick / GMC.

I highly recommend this dealership to anyone considering
I highly recommend this dealership to anyone considering buying a vehicle. I live in Colorado and found one of their vehicles online. When I called, William picked up the phone and gave me honest answers to every concern I had. Soon after, I was contacted by the Sales Manager, Jason, who made me feel even more confident about the process. They picked me up from the airport, and everything — absolutely everything — was exactly as promised. From start to finish, this was hands down the best car-buying experience I’ve ever had. These guys are true professionals. If they give you their word, you can trust they’ll stand by it. Going forward, this will be the first dealership I check when shopping for any future vehicles — especially high-end ones — because I know I’m dealing with a team that values honesty and integrity above all. Thank you again for an outstanding experience!
