I live in Utah but recently bought an Escalade from
I live in Utah but recently bought an Escalade from Halladay Cadillac in Cheyenne and honestly, I was just super impressed with everyone. You can tell these guys know how to treat people right and run a solid, honest dealership. They picked me up at the Denver airport and drove me up to Cheyenne. After the sale, on my way home I noticed that the USB and HDMI ports in the vehicle did not work. It was unexpected, but the way they handled it really meant a lot. The repair wasn't cheap but they didn’t make excuses, they just took care of it and made things right. That kind of service is rare, and it meant a lot. It was clear they stood behind what they sold, and that goes a long way. I’d absolutely buy from them again and recommend them to anyone who wants to work with good people who actually care about doing the right thing. Special thanks to Bryon the salesman who was super helpful and never pushy and John the sales manager who was a pleasure to work with in getting the issue resolved after the purchase and Shawn Smith the GM for standing behind the sale and being willing to take care of it. If I could give more than 5 stars I would.
This is a luxury suv with plenty of room.
This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

2021 Yukon XL Denali Diesel 3.0
This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

Better sales experience this time - no issues
In the interest of fairness, I wanted to follow up on the negative review I left on Dec 20, 2022. The dealership, specifically Shaun A reached out to me and apologized for the miscommunication and inconvenience they put us through. And after some discussion, he agreed to lower the price of the the Edge that we were interested in by $500. It was an overall good deal and my wife and I accepted the offer and completed the sale that same day. No issues with the sales process and the paperwork was handled professionally and efficiently.

I recently purchased my BMW XM from Kia of Riverdale, and I couldn’t be happier with the experience. From the moment I walked in, the customer service was top-notch, and I want to give a special shoutout to Pete O’Brien. Pete was not only incredibly professional and knowledgeable but also funny, engaging, and truly a joy to work with. He made the entire buying process smooth and stress-free, and his personality kept things light and enjoyable. I also traded in my previous car, and Pete went above and beyond to make sure I got the best possible deal. He’s the kind of person who genuinely looks out for his customers and ensures you leave with a great car and an even better deal. If you're in the market for a vehicle — especially if you’re looking to trade in — I highly recommend going to Kia of Riverdale and asking for Pete. Outstanding service, a great deal, and a memorable experience. Thank you, Pete, for making my BMW XM purchase such a positive one!

Our salesperson was Koby.
Our salesperson was Koby. Very nice and not pushy. I was assisting my daughter in shopping for an MPV/minivan (her 3rd little boy is due next month). She wanted a loaded hybrid, so the candidates were the Kia Carnival Prestige OR the Toyota Sienna Platinum. (No interest in the Chrysler hybrid minivan) CR had rated the 2024 Kia Carnival their # 1 minivan BEFORE the 2025 improved, refreshed model...CR had Sienna rated 2nd. We EASILY PREFERRED the Kia Carnival Prestige over Sienna Platinum, and we have owned a lot of Toyotas and Lexuses...we drove up in her Lexus 450H. The Kia looked better inside and outside, it had great tech, it drove and handled well, and has a lot of safety features for her growing family. The car she wanted was actually at the Greenway Franklin dealer, but they moved it up to Antioch/Hickory Hollow (closer to home in D/T Nashville) where she finalized the deal promptly. A little side note...there was no new loaded Platinum Sienna to be had. Toyota seems to have opted for "planned scarcity" -- dealers who get one are proffering them at $5k-10k over MSRP! We laugh at such a notion-- we would have chosen the Carnival Prestige STRAIGHT UP over the Sienna Platinum (even if they were priced the same), and this comes from a family who has had myriad Toyota products since 1987. We were pleased all around with our shopping and buying experience at Greenway Kia of Hickory Hollow, and can recommend salesman Kobe.

For some reason Mark's name is not on the list where it says, "Choose their name," but Mark was so helpful, patient, explained the process clearly and was very professional. I highly recommend him and would work with him and his team again. I would hope for a promotion for him Hyundai. :)
